An-Nahl 16:70

وَٱللَّهُ خَلَقَكُمْ ثُمَّ يَتَوَفَّىٰكُمْ ۚ وَمِنكُم مَّن يُرَدُّ إِلَىٰٓ أَرْذَلِ ٱلْعُمُرِ لِكَىْ لَا يَعْلَمَ بَعْدَ عِلْمٍۢ شَيْـًٔا ۚ إِنَّ ٱللَّهَ عَلِيمٌۭ قَدِيرٌۭ

It is Allah who creates you and takes your souls at death; and of you there are some who are sent back to a feeble age, so that they know nothing after having known (much): for Allah is All-Knowing, All-Powerful.
