The Repentance
لَوْ خَرَجُوا۟ فِيكُم مَّا زَادُوكُمْ إِلَّا خَبَالًا وَلَأَوْضَعُوا۟ خِلَـٰلَكُمْ يَبْغُونَكُمُ ٱلْفِتْنَةَ وَفِيكُمْ سَمَّـٰعُونَ لَهُمْ ۗ وَٱللَّهُ عَلِيمٌۢ بِٱلظَّـٰلِمِينَ
Had they gone forth with you, they would not have increased you except in confusion, and they would have been active among you, seeking [to cause] you fitnah. And among you are avid listeners to them. And Allah is Knowing of the wrongdoers.

إِنَّمَا يَسْتَـْٔذِنُكَ ٱلَّذِينَ لَا يُؤْمِنُونَ بِٱللَّهِ وَٱلْيَوْمِ ٱلْـَٔاخِرِ وَٱرْتَابَتْ قُلُوبُهُمْ فَهُمْ فِى رَيْبِهِمْ يَتَرَدَّدُونَ
Only those would ask permission of you who do not believe in Allah and the Last Day and whose hearts have doubted, and they, in their doubt, are hesitating.
۞ وَلَوْ أَرَادُوا۟ ٱلْخُرُوجَ لَأَعَدُّوا۟ لَهُۥ عُدَّةً وَلَـٰكِن كَرِهَ ٱللَّهُ ٱنۢبِعَاثَهُمْ فَثَبَّطَهُمْ وَقِيلَ ٱقْعُدُوا۟ مَعَ ٱلْقَـٰعِدِينَ
And if they had intended to go forth, they would have prepared for it [some] preparation. But Allah disliked their being sent, so He kept them back, and they were told, "Remain [behind] with those who remain."
لَقَدِ ٱبْتَغَوُا۟ ٱلْفِتْنَةَ مِن قَبْلُ وَقَلَّبُوا۟ لَكَ ٱلْأُمُورَ حَتَّىٰ جَآءَ ٱلْحَقُّ وَظَهَرَ أَمْرُ ٱللَّهِ وَهُمْ كَـٰرِهُونَ
They had already desired dissension before and had upset matters for you until the truth came and the ordinance of Allah appeared, while they were averse.
وَمِنْهُم مَّن يَقُولُ ٱئْذَن لِّى وَلَا تَفْتِنِّىٓ ۚ أَلَا فِى ٱلْفِتْنَةِ سَقَطُوا۟ ۗ وَإِنَّ جَهَنَّمَ لَمُحِيطَةٌۢ بِٱلْكَـٰفِرِينَ
And among them is he who says, "Permit me [to remain at home] and do not put me to trial." Unquestionably, into trial they have fallen. And indeed, Hell will encompass the disbelievers.
