Quran 16:70 An-Nahl, ayah 70 of 128

وَٱللَّهُ خَلَقَكُمْ ثُمَّ يَتَوَفَّىٰكُمْ ۚ وَمِنكُم مَّن يُرَدُّ إِلَىٰٓ أَرْذَلِ ٱلْعُمُرِ لِكَىْ لَا يَعْلَمَ بَعْدَ عِلْمٍ شَيْـًٔا ۚ إِنَّ ٱللَّهَ عَلِيمٌ قَدِيرٌ ۝٧٠

16:70 And Allah createth you, then causeth you to die, and among you is he who is brought back to the most abject stage of life, so that he knoweth nothing after (having had) knowledge. Lo! Allah is Knower, Powerful.
