١٦ : ٧٠
وَٱللَّهُ خَلَقَكُمۡ ثُمَّ يَتَوَفَّىٰكُمۡۚ وَمِنكُم مَّن يُرَدُّ إِلَىٰٓ أَرۡذَلِ ٱلۡعُمُرِ لِكَيۡ لَا يَعۡلَمَ بَعۡدَ عِلۡمٖ شَيۡـًٔاۚ إِنَّ ٱللَّهَ عَلِيمٞ قَدِيرٞ
Allah has created you, then He causes you to die. Among you are some who are left to reach the most decrepit age, so that they may know nothing after having known much. Indeed, Allah is All-Knowing, Most Capable.
