The Sealed Hearts (Kaafir):

The sealed heart is the heart of a kaafir who will never believe in Islam. Allah spoke about this in 2:6-7

Verily, those who disbelieve, it is the same to them whether you (O Muhammad Peace be upon him ) warn them or do not warn them, they will not believe. Allāh has set a seal on their hearts and on their hearings, (i.e. they are closed from accepting Allāh's Guidance), and on their eyes there is a covering. Theirs will be a great torment. (Al-Baqarah 2:6-7)

The people with sealed hearts worship their evil and corrupted desires. So their lust has become their god. Hence, Allah says:

Have you seen him who takes his own lust (vain desires) as his ilāh (god), and Allāh knowing (him as such), left him astray, and sealed his hearing and his heart, and put a cover on his sight. Who then will guide him after Allāh? Will you not then remember? (Al-Jathiyah 45:23)

Whenever the heart of a kaafir is sealed up, Islam will not enter and kufr will not come out.

1.This was the plight of Nimrod, the man who threw Abraham into the fire.

2.This was the plight of the Pharoah, the man who rejected the message of Moses after seeing the 9 signs of Moses.

3.This was the plight of Abu Lahab, the Uncle of the Prophet (saw) who rejected the message of the Rasool (saw).

4.This was the plight of Abu Jahll, the commander-in-chief for Quraysh at the battle of Badr.

5.This is the plight of most Jews today. Even though they know Muhammad (saw) is the messenger of Allah, they reject him in the name of asabiyah.

Allah spoke about the Jews in the following Quranic verse:

And they, the Jews, say, "Our hearts are wrapped (i.e. do not hear or understand Allāh's Word)." Nay, Allāh has cursed them for their disbelief, so little is that which they believe. (Al-Baqarah 2:8)

This Ayah tells you that Jews (past and present) most will not believe. Most of them have a heart that is sealed up.

A sealed heart is rebellious to the haqq and you are not allowed to give dawah to a person whose heart is sealed this person is harshly argumentative to the haqq. You are only allowed to give dawa to a person who shows an interested in Islam. Hence, Allah said:

So give admonition if it benefits the listener; 87:9

Allah said here "IF" it benefits the person. You are only allowed to give dawah to a person who appreciates the dawah. Otherwise it is like throwing gold to swine, you are wasting your time to a person not worth a dime. It is haram to waste your time. Hence, Allah said:

Verily, spendthrifts are brothers of the Shayatīn (devils), and the Shaitān (Devil Satan) is ever ungrateful to his Lord. (Al-Isra 17:27)

This is why you are not allowed to give dawah to a person whose heart is sealed. If you respect yourself, don't waste your time with a person rebellious to the haqq. The best way to spread Islam is not dawa. The best way is through jihad. Hence, Allah said:

And fight them until there is no more Fitnah (disbelief and polytheism: i.e. worshipping others besides Allah) and the religion (worship) will all be for Allah Alone [in the whole of the world[]]. But if they cease (worshipping others besides Allah), then certainly, Allah is All-Seer of what they do. (Al-Anfal 8:39)

Fight against those who (1) believe not in Allah, (2) nor in the Last Day, (3) nor forbid that which has been forbidden by Allah and His Messenger (4) and those who acknowledge not the religion of truth (i.e. Islam) among the people of the Scripture (Jews and Christians), until they pay the Jizyah[] with willing submission, and feel themselves subdued. (At-Tawbah 9:29)

Dawah is the method for people who are weak. Shaikh bin Baaz said you don't understand the ayah about no compulsion in religion. He said it means either you embrace Islam or die. You are allowed to force a pagan to become Muslim because it is better for someone to be a Muslim and worship Allah alone. You can't take jizya from people who are not Christian or Jew; therefore, you are allowed to force them to take shahada.

A man asked Shaykh Bin Baaz about the permissibility of forcing a kaafir to embrace Islam. The following is the question of the person and the fatwa of the Shaykh [RA]:

Some friends say that whoever does not enter Islam, that is his choice and he should not be forced to become Muslim, quoting as evidence the verses in which Allaah says (interpretation of the meaning): “And had your Lord willed, those on earth would have believed, all of them together. So, will you (O Muhammad) then compel mankind, until they become believers” [Yoonus 10:99]

“There is no compulsion in religion” [al-Baqarah 2:256]

What is your opinion concerning that?.

The scholars explained that these two verses, and other similar verses, have to do with those from whom the jizyah may be taken, such as Jews, Christians and Magians (Zoroastrians). They are not to be forced, rather they are to be given the choice between becoming Muslim or paying the jizyah.

Other scholars said that this applied in the beginning, but was subsequently abrogated by Allaah’s command to fight and wage jihad. So whoever refuses to enter Islam should be fought when the Muslims are able to fight, until they either enter Islam or pay the jizyah if they are among the people who may pay jizyah. The kuffaar should be compelled to enter Islam if they are not people from whom the jizyah may be taken, because that will lead to their happiness and salvation in this world and in the Hereafter. Obliging a person to adhere to the truth in which is guidance and happiness is better for him than falsehood. Just as a person may be forced to do the duty that he owes to other people even if that is by means of imprisonment or beating, so forcing the kaafirs to believe in Allaah alone and enter into the religion of Islam is more important and more essential, because this will lead to their happiness in this world and in the Hereafter. This applies unless they are People of the Book, i.e., Jews and Christians, or Magians, because Islam says that these three groups may be given the choice: they may enter Islam or they may pay the jizyah and feel themselves subdued.

Some of the scholars are of the view that others may also be given the choice between Islam and jizyah, but the most correct view is that no others should be given this choice, rather these three groups are the only ones who may be given the choice, because the Prophet (peace and blessings of Allaah be upon him) fought the kuffaar in the Arabian Peninsula and he only accepted their becoming Muslim. And Allaah says (interpretation of the meaning):

“But if they repent [by rejecting Shirk (polytheism) and accept Islamic Monotheism] and perform As-Salaah (Iqaamat-as-Salaah), and give Zakaah, then leave their way free. Verily, Allaah is Oft-Forgiving, Most Merciful”[al-Tawbah 9:5]

He did not say, “if they pay the jizyah”. The Jews, Christians and Magians are to be asked to enter Islam; if they refuse then they should be asked to pay the jizyah. If they refuse to pay the jizyah then the Muslims must fight them if they are able to do so. Allaah says (interpretation of the meaning):

“Fight against those who (1) believe not in Allaah, (2) nor in the Last Day, (3) nor forbid that which has been forbidden by Allaah and His Messenger (Muhammad), (4) and those who acknowledge not the religion of truth (i.e. Islam) among the people of the Scripture (Jews and Christians), until they pay the Jizyah with willing submission, and feel themselves subdued”[al-Tawbah 9:29]

And it was proven that the Prophet (peace and blessings of Allaah be upon him) accepted the jizyah from the Magians, but it was not proven that the Prophet (peace and blessings of Allaah be upon him) or his companions (may Allaah be pleased with them) accepted the jizyah from anyone except the three groups mentioned above. [Majmoo’ Fataawa wa Maqaalaat li’l-Shaykh Ibn Baaz, 6/219]

It is mandatory to have health insurance and car insurance in darul Harb. What's more important? To have obamacare or to believe in Allah? To drive with car insurance or to worship Allah alone? So if you can force a person to have insurance; likewise, you can force a person to worship Allah alone. Because the right of Allah is more important than the right of humans or the rights of a kaafir state. Hence, Shaykh Bin Baaz [RA] said:

The kuffaar should be compelled to enter Islam if they are not people from whom the jizyah may be taken, because that will lead to their happiness and salvation in this world and in the Hereafter. Obliging a person to adhere to the truth in which is guidance and happiness is better for him than falsehood. Just as a person may be forced to do the duty that he owes to other people even if that is by means of imprisonment or beating, so forcing the kaafirs to believe in Allaah alone and enter into the religion of Islam is more important and more essential, because this will lead to their happiness in this world and in the Hereafter. [Majmoo’ Fataawa wa Maqaalaat li’l-Shaykh Ibn Baaz, 6/219]

It is worthy of mentioning that only the Islamic State has the authority to force a kaafir to embrace Islam. Muslims who are living in Darul Harb or Darul Kufr are not allowed to force their kuffar neighbors to embrace Islam.

When Shaykh Bin Baaz gives a fatwa he doesn't write kufr because he was careful about his legacy.

The blind man is not the man who is blind in his eyes. The real blind man is blind in his heart. Hence, Allah said:

Have they not travelled through the land, and have they hearts wherewith to understand and ears wherewith to hear? Verily, it is not the eyes that grow blind, but it is the hearts which are in the breasts that grow blind. (Al-Hajj 22:46)

The Prophet (saw) said something similar in the following Hadith about the blind hypocrite:

The Messenger of Allah (SAW) said to his men: "Which man of you can lead us to where the people (i.e. the idolaters) are, along a short track that does not pass by them?" Abu Khaithama said: "O Messenger of Allah (SAW), I am the man you need." Then he chose a short track that led to Uhud passing by Harrah Bani Harithah and their farms, leaving the idolaters' army westwards. On their way they passed by Ha'it (i.e. the field) of Marba' bin Qaizi, who was a blind hypocrite. When Marba' felt and realized that they were the Prophetic army, he started throwing earth at their faces, so they rushed to kill him, but the Prophet (SAW) said: "Do not kill him. He is blind in heart and eyes."[Seerah Ibn Hisham (2/65)]

When you are blind in your heart, it means your heart is sealed. Some people whose hearts are sealed fight Islam like Nimrod, the Pharaoh, Abu Lahab and Abu Jahl. Their fighting will be with propaganda warfare. They will slander your name as they used to slander the Prophet (saw). So Allah revealed the following Surah:

Woe to every slanderer and backbiter. Who has gathered wealth and counted it, He thinks that his wealth will make him last forever! (Al-Humuzah 104:1-3)

They will use the entertainment industry to fight Islam

And of mankind is he who purchases idle talks (i.e.music, singing, etc.) to mislead (men) from the Path of Allāh without knowledge, and takes it (the Path of Allāh, the Verses of the Qur'ān) by way of mockery. For such there will be a humiliating torment (in the Hell-fire). (Luqman 31:6)

When they make a mockery of the deen it's called smear, sneer, and jeer. This is all apart of the propaganda warfare.

They will also use the cultural warfare to fight you. Their Jerry Springer culture of no morals and they are shameless about their degeneracy and debauchery

Never will the Jews nor the Christians be pleased with you (O Muhammad Peace be upon him ) till you follow their religion. Say: "Verily, the Guidance of Allāh (i.e. Islāmic Monotheism) that is the (only) Guidance. (Al-Baqarah 2:120)

The infidels would like you to compromise on your religion to please them. They claim, by doing so, it shows that you are courteous. In this regard, Allah said:

They wish that you should compromise (in religion out of courtesy) with them, so they (too) would compromise with you. (Al-Qalam 68:9)

They will fight you economically with sanctions and embargo. This is called economic warfare. They think if they make you suffer object poverty, you will apostate from Islam. Hence, Allah said:

Shaitān (Satan) threatens you with poverty and orders you to commit Fahshā (evil deeds, illegal sexual intercourse, sins etc.); whereas Allāh promises you Forgiveness from Himself and Bounty, and Allāh is All-Sufficient for His creatures' needs, All-Knower. (Al-Baqarah 2:26

The Holy Prophet (saw) told us in the following Hadith that poverty can lead to kufr:

Anas Ibn Malik narrated the Messenger of Allah (SAW) said: “Poverty, in all probability, leads to unbelief (kufr)...” [al-Bayhaqi narrated in 'Shu’ab al-Eemaan' (9/12) No. 6188 and Abu Na'eem narrated in 'Hileeyat al-Awwleeyah' (3/109)]

They will also fight you with psychological warfare. They make you think you should throw in the towel and give up the Jihad against them because they have weapons of mass destruction which we do not have. Don't think warfare is only one type. They will wage political warfare by isolating a country and call it a rogue state and an axes of evil.

They will also wage spiritual warfare against you. They have websites saying they found contradictions in Quran. They will write books to cast doubt on Islam. They will pay actors to pretend to be x-Muslims even though these actors are Jews and Christians. All these strategies are called spiritual warfare. Allah told you that the kuffar would like you to apostate from Islam because they envy you for your deen. Hence, Allah said:

Many of the people of the Scripture (Jews and Christians) wish that if they could turn you away as disbelievers after you have believed, out of envy from their ownselves, even, after the truth (that Muhammad Peace be upon him is Allah's Messenger) has become manifest unto them. (Al-Baqarah 2:109)

Why do you think China banned Ramadan? They banned Ramadan because they want the Muslims to apostate from Islam so that they and the Muslims can be on the same even keel. In this regard, Allah said:

They wish that you reject Faith, as they have rejected (Faith), and thus that you all become equal (like one another). (An-Nisa 4:89)

Another way they fight you is by way of Military Warfare. They even bomb schools and hospitals. It includes the use of chemical weapons. Many children are born deformed in Iraq and Afghanistan because the kuffar used chemical warfare against them. About these infidels fighting us, Allah said:

And they will never cease fighting you until they turn you back from your religion (Islāmic Monotheism) if they can. And whosoever of you turns back from his religion and dies as a disbeliever, then his deeds will be lost in this life and in the Hereafter, and they will be the dwellers of the Fire. They will abide therein forever." (Al-Baqarah 2:217)

Seven types of warfares are mentioned above. The people whose heart are sealed fight Islam with these seven types of warfares, past and present. This is why the commander-in-chief, Abu Jahl, came to fight Islam at the battle of Badr. The hypocrites belong to this second category of people whose hearts are sealed. Allah spoke about them in the following Ayah:

In their hearts is a disease (of doubt and hypocrisy) and Allāh has increased their disease. A painful torment is theirs because they used to tell lies. (Al-Baqarah 2:10)

Because they belong to this second category, they will be in the bottom of the hellfire like Allah said:

Verily, the hyprocrites will be in the lowest depths (grade) of the Fire; no helper will you find for them. (An-Nisa 4:145)

Did you know Allah sometimes comes between a man and his heart?

and know that Allah comes in between a person and his heart (i.e. He prevents an evil person to decide anything). And verily to Him you shall (all) be gathered. (Al-Anfal 8:24)

Sometimes a man is evil to the core, so Allah prevents him from making a decision. So many countries have the atomic bomb in the world today. The world would have been destroyed if Allah didn’t come between a man and his decisions. Hence, Allah said:

Then, after that, your hearts were hardened and became as stones or even worse in hardness. And indeed, there are stones out of which rivers gush forth, and indeed, there are of them (stones) which split asunder so that water flows from them, and indeed, there are of them (stones) which fall down for fear of Allāh. And Allāh is not unaware of what you do. (Al-Baqarah 2:74)

These people whose hearts are sealed are cowards. They spent millions to train their troops but do not send any to fight the Islamic State, yet they brag about how they have trained their troops with state of the art weaponry. They also brag about how their troops graduated from the most advanced military academies in the world. They are all cowards. In this regard Allah said:

We shall cast terror into the hearts of those who disbelieve, because they joined others in worship with Allah, for which He had sent no authority; their abode will be the Fire and how evil is the abode of the Zālimûn (polytheists and wrongdoers). (Aali Imran 3:151)

How can they face the mujahideen with atheist, devil worshippers and homosexuals in their army? Their army has no barakah. Angels don't help atheist, devil worshippers and homosexuals. Allah said he is the friend and helper of those who believe in the following Ayah:

Allah is the Walī (Protector or Guardian) of those who believe. He brings them out from darkness into light. But as for those who disbelieve, their Auliyā (supporters and helpers) are Tāghût [false deities and false leaders, etc.], they bring them out from light into darkness. Those are the dwellers of the Fire, and they will abide therein forever. (Al-Baqarah 2:257)

Those whose hearts are sealed are cowards. For them to fight the mujahideen, they have to take drugs and drink alcohol. When the kurds camp are taken over by the Mujahideen, it is full of Jack Daniel’s (alcohol) which they use to give themselves Dutch Courage (a courage that last an hour or two).

And Almighty Allah Knows Best..
