وَلَئِنْ أَذَقْنَٰهُ رَحْمَةًۭ مِّنَّا مِنۢ بَعْدِ ضَرَّآءَ مَسَّتْهُ لَيَقُولَنَّ هَٰذَا لِى وَمَآ أَظُنُّ ٱلسَّاعَةَ قَآئِمَةًۭ وَلَئِن رُّجِعْتُ إِلَىٰ رَبِّىٓ إِنَّ لِى عِندَهُۥ لَلْحُسْنَىٰ ۚ فَلَنُنَبِّئَنَّ ٱلَّذِينَ كَفَرُوا۟ بِمَا عَمِلُوا۟ وَلَنُذِيقَنَّهُم مِّنْ عَذَابٍ غَلِيظٍۢ
And verily, if We cause him to taste mercy after some hurt that hath touched him, he will say: This is my own; and I deem not that the Hour will ever rise, and if I am brought back to my Lord, I surely shall be better off with Him - But We verily shall tell those who disbelieve (all) that they did, and We verily shall make them taste hard punishment.
Surah Fussilat(41:50)
