Quran 7:201

Surah Al-Araf, Verse 201:
إِنَّ الَّذِينَ اتَّقَوْا إِذَا مَسَّهُمْ طَائِفٌ مِّنَ الشَّيْطَانِ تَذَكَّرُوا فَإِذَا هُم مُّبْصِرُونَ
Verily, those who are Al-Muttaqûn (the pious - see V.2:2), when an evil thought comes to them from Shaitân (Satan), they remember (Allâh), and (indeed) they then see (aright). Surah An-Nisa, Verse 27:
وَاللَّهُ يُرِيدُ أَن يَتُوبَ عَلَيْكُمْ وَيُرِيدُ الَّذِينَ يَتَّبِعُونَ الشَّهَوَاتِ أَن تَمِيلُوا مَيْلًا عَظِيمًا
Allâh wishes to accept your repentance, but those who follow their lusts, wish that you (believers) should deviate tremendously away from the Right Path. Surah An-Nisa, Verse 28:
يُرِيدُ اللَّهُ أَن يُخَفِّفَ عَنكُمْ وَخُلِقَ الْإِنسَانُ ضَعِيفًا
Allâh wishes to lighten (the burden) for you; and man was created weak (cannot be patient to leave sexual intercourse with woman). Surah Az-Zumar, Verse 53:
قُلْ يَا عِبَادِيَ الَّذِينَ أَسْرَفُوا عَلَىٰ أَنفُسِهِمْ لَا تَقْنَطُوا مِن رَّحْمَةِ اللَّهِ إِنَّ اللَّهَ يَغْفِرُ الذُّنُوبَ جَمِيعًا إِنَّهُ هُوَ الْغَفُورُ الرَّحِيمُ
Say: "O 'Ibâdî (My slaves) who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the Mercy of Allâh, verily Allâh forgives all sins. Truly, He is Oft-Forgiving, Most Merciful. Surah Aal-e-Imran, Verse 135:
وَالَّذِينَ إِذَا فَعَلُوا فَاحِشَةً أَوْ ظَلَمُوا أَنفُسَهُمْ ذَكَرُوا اللَّهَ فَاسْتَغْفَرُوا لِذُنُوبِهِمْ وَمَن يَغْفِرُ الذُّنُوبَ إِلَّا اللَّهُ وَلَمْ يُصِرُّوا عَلَىٰ مَا فَعَلُوا وَهُمْ يَعْلَمُونَ
And those who, when they have committed Fahishah (illegal sexual intercourse etc.) or wronged themselves with evil, remember Allâh and ask forgiveness for their sins; - and none can forgive sins but Allâh - And do not persist in what (wrong) they have done, while they know. Surah Al-Baqara, Verse 152:
فَاذْكُرُونِي أَذْكُرْكُمْ وَاشْكُرُوا لِي وَلَا تَكْفُرُونِ
Therefore remember Me (by praying, glorifying, etc.).I will remember you, and be grateful to Me (for My countless Favours on you) and never be ungrateful to Me.
