وَهُوَ الَّذِي يَتَوَفَّاكُم بِاللَّيْلِ وَيَعْلَمُ مَا جَرَحْتُم بِالنَّهَارِ ثُمَّ يَبْعَثُكُمْ فِيهِ لِيُقْضَىٰ أَجَلٌ مُّسَمًّى ۖ ثُمَّ إِلَيْهِ مَرْجِعُكُمْ ثُمَّ يُنَبِّئُكُم بِمَا كُنتُمْ تَعْمَلُونَ
Wahuwa allathee yatawaffakum biallayli wayaAAlamu ma jarahtum bialnnahari thumma yabAAathukum feehi liyuqda ajalun musamman thumma ilayhi marjiAAukum thumma yunabbiokum bima kuntum taAAmaloona
It is He who doth take your souls by night, and hath knowledge of all that ye have done by day: by day doth He raise you up again; that a term appointed be fulfilled; In the end unto Him will be your return; then will He show you the truth of all that ye did.
