Quran 41:50

وَلَٮِٕنۡ أَذَقۡنَـٰهُ رَحۡمَةً۬ مِّنَّا مِنۢ بَعۡدِ ضَرَّآءَ مَسَّتۡهُ لَيَقُولَنَّ هَـٰذَا لِى وَمَآ أَظُنُّ ٱلسَّاعَةَ قَآٮِٕمَةً۬ وَلَٮِٕن رُّجِعۡتُ إِلَىٰ رَبِّىٓ إِنَّ لِى عِندَهُ ۥ لَلۡحُسۡنَىٰ‌ۚ فَلَنُنَبِّئَنَّ ٱلَّذِينَ كَفَرُواْ بِمَا عَمِلُواْ وَلَنُذِيقَنَّهُم مِّنۡ عَذَابٍ غَلِيظٍ۬ ٥٠

And when we bless him after suffering some adversity, he says, "This belongs to me. I do not believe that the Hour will ever come to pass. Even if I am returned to my Lord, I will find at Him better things." Most certainly, we will inform the disbelievers of all their works, and will commit them to severe retribution.
