Qur'an 20:121

فَأَكَلَا مِنْهَا فَبَدَتْ لَهُمَا سَوْءَٰتُهُمَا وَطَفِقَا يَخْصِفَانِ عَلَيْهِمَا مِن وَرَقِ ٱلْجَنَّةِ ۚ وَعَصَىٰٓ ءَادَمُ رَبَّهُۥ فَغَوَىٰ

Then they twain ate thereof, so that their shame became apparent unto them, and they began to hide by heaping on themselves some of the leaves of the Garden. And Adam disobeyed his Lord, so went astray.
