ٱلَّذِينَ تَتَوَفَّىٰهُمُ ٱلْمَلَٰٓئِكَةُ ظَالِمِىٓ أَنفُسِهِمْ ۖ فَأَلْقَوُا۟ ٱلسَّلَمَ مَا كُنَّا نَعْمَلُ مِن سُوٓءٍۭ ۚ بَلَىٰٓ إِنَّ ٱللَّهَ عَلِيمٌۢ بِمَا كُنتُمْ تَعْمَلُونَ
Whom the angels cause to die while they are wronging themselves. Then will they make full submission (saying): We used not to do any wrong. Nay! Surely Allah is Knower of what ye used to do.
