Quran 41:50 Fussilat, ayah 50 of 54

وَلَئِنْ أَذَقْنَـٰهُ رَحْمَةً مِّنَّا مِنۢ بَعْدِ ضَرَّآءَ مَسَّتْهُ لَيَقُولَنَّ هَـٰذَا لِى وَمَآ أَظُنُّ ٱلسَّاعَةَ قَآئِمَةً وَلَئِن رُّجِعْتُ إِلَىٰ رَبِّىٓ إِنَّ لِى عِندَهُۥ لَلْحُسْنَىٰ ۚ فَلَنُنَبِّئَنَّ ٱلَّذِينَ كَفَرُوا۟ بِمَا عَمِلُوا۟ وَلَنُذِيقَنَّهُم مِّنْ عَذَابٍ غَلِيظٍ ۝٥٠

41:50 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.
