Death and life are Created by Allah

Bismillahi Rahmani raheem. Allahumma Swalli Ala Sayyidina Muhammadin Wa Ala Aali Sayyidina Muhammadin Wa Sallim

Death and life are Created by Allah for: [Quran 67.2]. He Who has created death and life, so that He may try you (and demonstrate to yourselves) which of you is better in deeds. And He is the All-Glorious with irresistible might (Whose will none can frustrate), the All-Forgiving (Who forgives many of His servants' sins so that they learn from being tested);

Allah placed the Spirit below the Ego in the heart, and placed ego on head, above the heart.As Allah says in Quran 67.2 and in 5:35 , the Struggle (Jihad) is to conquer the Ego and step the bring the ego down and place the authority of the heart above ego!
Allah says that the spirit thogh created in best stature (95:4 We have certainly created man in the best of stature;), God returned it to the lowest place of the low one (ego). in Quran 95:5 Then We return him to the lowest of the low.

Brain is the place for mind and ego in which Thoughts,Ideas, Emotions, Anger, Jealousy,hatred etc are running and changing like a shifting shadow!

It is easy for ego to descend and corrupt,like a storm, like a volcano, like a landslide and corrupt the heart,which is the house of spirit.

It is a great struggle for the spirit to ascend and purify the ego and dominate the entire person!. It is like climbing a big mountain,or swimming through an ocean filled with gigantic waves (filled with millions of thoughts, ideas and physical desires),, or like fighting alone with 1000s of wolves and beasts.
It is not possible to conquer the ego without the spiritual support coming from heavens. Allah says:[Quran 5:35] O ye who believe! Do your duty to Allah, seek the means of approach unto Him, and strive with might and main in his cause: that ye may prosper.

The Spirit Stays in the Heart as the Prophet (s.a.w) stayed in the Cave with Abu Bakar Siddiq (R.A), though some others may enter in it, yet it has placed it's allegiance to Allah and His Prophet (alaihiswalathu wa salam). As for Abu Bakar Siddiq (R.A), the Prophet (alaihiswalathu wa salam) was his guide and light in the cave. For the Spirit requires a guide appointed from the heavens.

Allah says: 9:40 If ye help not (your leader), (it is no matter): for Allah did indeed help him, when the Unbelievers drove him out: he had no more than one companion; they two were in the cave, and he said to his companion, "Have no fear, for Allah is with us": then Allah sent down His peace upon him, and strengthened him with forces which ye saw not, and humbled to the depths the word of the Unbelievers. But the word of Allah is exalted to the heights: for Allah is Exalted in might, Wise.

The Spirit when following the Prophet (s.a.w) and appointed helper (ulool amri , Quran 17:80 and 4:59) receive the blessings and aid, and become tranquil , though the enemies are now on power. As for the tasawwuf, even if the ego is in power, a man who follow Allah, His Prophet (s.a.w) and those who are in authority, will receive aid from the spiritual means to overpower his ego!

Quran 17:80 Say: "O my Lord! Let my entry be by the Gate of Truth and Honor, and likewise my exit by the Gate of Truth and Honor; and grant me from Thy Presence an authority to aid (me)."

The enemies of the Spirit, those who work against their Soul (Spirit), those who work against the Prophet Muhammad- the Last messenger of Allah and the leader of all Prophets, leader of Moses (A.S) and Jesus Christ (A.S). They are cut off from their spirit, holy spirit and God Almighty! The misguided sects in Islam, they also cut off. Understand this truth and surrender, Submit and Sacrifice, leave all false hood!
Allah says: 108:3 "O Muhammad Indeed, your enemy is the one cut off."
Allah says 91:9-10 He has succeeded who purifies it,And he will indeed fail who corrupts it.
Sahih Bukhari: PProphet (alaihiswalathu wa salam) said: ‘Surely there is in the body a small piece of flesh; if it is good, the whole body is good, and if it is corrupted, the whole body is corrupted, and that is surely the heart’. (Sahih Bukhari)

CONSULT WITH THE PIOUS PEOPLE WHOSE HEARTS ARE PURIFIED FROM EVERYTHING EXCEPT ALLAH AND THE PROPHET (S.A.W)
On the authority of an-Nawas bin Sam’an (may Allah be pleased with him), that the Prophet (peace and blessings of Allah be upon him) said:Righteousness is in good character, and wrongdoing is that which wavers in your soul, and which you dislike people finding out about. [Muslim]

And on the authority of Wabisah bin Ma’bad (may Allah be pleased with him) who said: I came to the Messenger of Allah (peace and blessings of Allah be upon him) and he (peace and blessings of Allah be upon him) said, “You have come to ask about righteousness.” I said, “Yes.” He (peace and blessings of Allah be upon him) said, “Consult your heart. Righteousness is that about which the soul feels at ease and the heart feels tranquil. And wrongdoing is that which wavers in the soul and causes uneasiness in the breast, even though people have repeatedly given their legal opinion [in its favour].”
A good hadeeth transmitted from the musnads of the two imams, Ahmed bin Hambal and Al- Darimi, with a good chain of authorities (Imam Nawawi's 40 Hadith)

They are Awliya Allah (Friends of God) in Whom there is no falsehood remains, except "AL HAQQ"

Allah says about them: [17:81]And say, "Truth has come, and falsehood has departed. Indeed is falsehood, [by nature], ever bound to depart."

"Everything is falsehood, except Allah" (Hadith hasan)

The Prophet (s.a.w) says [Imma Nawawi 40 Hadith] : On the authority of Abu Hurayrah (may Allah be pleased with him) who said:
The Messenger of Allah (peace and blessings of Allah be upon him) said, “Verily Allah ta’ala has said: ‘Whosoever shows enmity to a wali of Mine, then I have declared war against him. And My servant does not draw near to Me with anything more loved to Me than the religious duties I have obligated upon him. And My servant continues to draw near to me with nafil (supererogatory) deeds until I Love him. When I Love him, I am his hearing with which he hears, and his sight with which he sees, and his hand with which he strikes, and his foot with which he walks. Were he to ask [something] of Me, I would surely give it to him; and were he to seek refuge with Me, I would surely grant him refuge.’ ” [Al-Bukhari]

Some misguided people misinterpret the above Hadith and say, the Hadith means , the servant do not hear or see or walk to any haram, this is what Allah becoming his hand ,feet, ears and eyes!
It is wrong interpretation. Because in such case how will Prophets and Imams Judge the people, they will have to hear, or witness the evil things or words or deeds, so that they can give statements to establish Islamic justice between persons and between parties! Without seeing or hearing about the issues concern Judgement and punishments, it is not possible in shari'ah to establish law and order. So do not get fooled by misguided interpretations!

Allah says about the Awliya Allah,: 50:16...and We are closer to him than [his] jugular vein.

They are the people of truth and bearers of true guidance, follow them.
Allah says in Quran [9:119] O you who have believed, fear Allah and be with those who are true.

Be with them and be patient with them.
Allah says: [4:59] O you who have believed, obey Allah and obey the Messenger and those in authority among you. And if you disagree over anything, refer it to Allah and the Messenger, if you should believe in Allah and the Last Day. That is the best [way] and best in result.

THEIR TRUE FOLLOWERS DO NOT REBEL AGAINST THEM NOR ARGUE, NOR SEPARATE FROM THE JAMAH THEY SAY:
Quran 2:285.. And they say, "We hear and we obey. [We seek] Your forgiveness, our Lord, and to You is the [final] destination."...

They are Selfless People. Follow them. Because Self has vanished in them and truth has come in them (refer to Quran 17:81)

Allah says: [Yaseen heart of Quran 36:21] Follow those who do not ask of you [any] payment, and they are [rightly] guided.

Their heart is dominant and their ego (falsehood) has perished, follow them.

It (Quran) guides them alone, so seek guidance from them, but those who do not follow them, are misguided, because every 73 sects reading Quran and all other books that is with them.

THEY ARE THE PEOPLE OF TAWHEED AND BEARERS OF PROPHETIC WISDOM AND HEIRS OF THE PROPHETS.
Allah says in Quran [3:18] Allah witnesses that there is no deity except Him, and [so do] the angels and those of knowledge - [that He is] maintaining [creation] in justice. There is no deity except Him, the Exalted in Might, the Wise.

THEY ARE SPIRITUAL SUCCESSORS OF THE PROPHETS, AND THE SPIRITUAL DEPUTIES:

3:26 Say, "O Allah , Owner of Sovereignty, You give sovereignty to whom You will and You take sovereignty away from whom You will. You honor whom You will and You humble whom You will. In Your hand is [all] good. Indeed, You are over all things competent.

by their authority, Allah bring dead hearts to life (faith), and by enmity to them Allah punish and send astray those who are transgressors!

It was narrated that Qays ibn Katheer said: “A man came from Madinah to Abu’l-Darda’ in Damascus and he said, ‘What brought you here, my brother?’ He said, ‘A hadeeth which I have heard that you narrate from the Messenger of Allaah (peace and blessings of Allaah be upon him).’ He said, ‘Have you come for any other reason?’ He said, ‘No.’ He said, ‘Have you come for trade?’ He said, ‘No. I have only come to seek this hadeeth.’ He said, ‘I heard the Messenger of Allaah (peace and blessings of Allaah be upon him) say, “Whoever follows a path to seek knowledge, Allaah will make easy for him the path to Paradise. The angels beat their wings in approval of the seeker of knowledge, and those who are in the heavens and on earth pray for forgiveness for the scholar, even the fish in the water. The superiority of the scholar over the worshipper is like the superiority of the moon over all other heavenly bodies. The scholars are the heirs of the Prophets, for the Prophets did not leave behind dinars or dirhams, rather they left behind knowledge, so whoever gains knowledge has gained great good fortune.’” (narrated by al-Tirmidhi, 2606; classed as sahihh by Wahhabi al-Albani).

THEY ARE THOSE UPON WHOM ALLAH HAS BESTOWED HIS FAVOR:
Which is Relationship to the Prophets, Wisdom ,Guidance and Assurance of the hereafter..
Allah says: 1:7 The path of those upon whom You have bestowed favor, not of those who have evoked [Your] anger or of those who are astray.

2:4-5 And who believe in the Revelation sent to thee, and sent before thy time, and (in their hearts) have the assurance of the Hereafter. Those are upon [right] guidance from their Lord, and it is those who are the successful.

IN THEIR HEART ALLAH SEND DOWN THE WISDOM OF QURAN:
59:21 Had We sent down this Quran on a mountain, you would certainly have seen it falling down, splitting asunder because of the fear of Allah, and We set forth these parables to men that they may reflect.

Others Have Quran with them with falsehood in their heart. But for them Quran is with them with Truth.
5:48 And unto thee have We revealed the Scripture with the truth, confirming whatever Scripture was before it, and a watcher over it. So judge between them by that which Allah hath revealed, and follow not their desires away from the truth which hath come unto thee. For each We have appointed a divine law and a traced-out way. Had Allah willed He could have made you one community. But that He may try you by that which He hath given you (He hath made you as ye are). So strive one with another in good works. Unto Allah ye will all return, and He will then inform you of that wherein ye differ.

On the authority of Tameem ibn Aus ad-Daree (ra):The Prophet (ﷺ) said, “The deen (religion) is naseehah (advice, sincerity).” We said, “To whom?” He (ﷺ) said, “To Allah, His Book, His Messenger, and to the leaders of the Muslims and their common folk.” [Muslim], Imam Nawawi in 40 Hadith

They give Dawah to the hearts, through Prophetic methods where the Soul receives it, others give preaching to the ears and eyes- the end of which is ego in the brain!, because ego receive it there in the brain!
Follow them and leave the people of false hood (people of empty deceit , ego and ignorance)!
