Quran 31:22-24

وَمَن يُسۡلِمۡ وَجۡهَهُ ۥۤ إِلَى ٱللَّهِ وَهُوَ مُحۡسِنٌ۬ فَقَدِ ٱسۡتَمۡسَكَ بِٱلۡعُرۡوَةِ ٱلۡوُثۡقَىٰ‌ۗ وَإِلَى ٱللَّهِ عَـٰقِبَةُ ٱلۡأُمُورِ (٢٢) وَمَن كَفَرَ فَلَا يَحۡزُنكَ كُفۡرُهُ ۥۤ‌ۚ إِلَيۡنَا مَرۡجِعُهُمۡ فَنُنَبِّئُهُم بِمَا عَمِلُوٓاْ‌ۚ إِنَّ ٱللَّهَ عَلِيمُۢ بِذَاتِ ٱلصُّدُورِ (٢٣) نُمَتِّعُهُمۡ قَلِيلاً۬ ثُمَّ نَضۡطَرُّهُمۡ إِلَىٰ عَذَابٍ غَلِيظٍ۬ (٢٤)
And whoever submits his face to Allah while he is a doer of good - then he has grasped the most trustworthy handhold. And to Allah will be the outcome of [all] matters.And whoever has disbelieved - let not his disbelief grieve you. To Us is their return, and We will inform them of what they did. Indeed, Allah is Knowing of that within the breasts.We grant them enjoyment for a little; then We will force them to a massive punishment.
