وَاللَّهُ خَلَقَكُم ثُمَّ يَتَوَفّاكُم ۚ وَمِنكُم مَن يُرَدُّ إِلىٰ أَرذَلِ العُمُرِ لِكَي لا يَعلَمَ بَعدَ عِلمٍ شَيئًا ۚ إِنَّ اللَّهَ عَليمٌ قَديرٌ

And Allah created you; then He will take you in death. And among you is he who is reversed to the most decrepit [old] age so that he will not know, after [having had] knowledge, a thing. Indeed, Allah is Knowing and Competent.
