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

“And so the two ate [of the fruit] thereof: and thereupon they became conscious of their nakedness and began to cover themselves with pieced-together leaves from the garden. And [thus] did Adam disobey his Sustainer, and thus did he fall into grievous error.”
