THAAHAA — Ayat 121
فَأَكَلَا مِنْهَا فَبَدَتْ لَهُمَا سَوْآتُهُمَا وَطَفِقَا يَخْصِفَانِ عَلَيْهِمَا مِن وَرَقِ الْجَنَّةِ وَعَصَى آدَمُ رَبَّهُ فَغَوَى
And Adam and his wife ate of it, and their private parts became apparent to them, and they began to fasten over themselves from the leaves of Paradise. And Adam disobeyed his Lord and erred.
Tafsir
{So they both ate} Adam and Eve {of it, and their private parts became visible to them} meaning that the front and back of each of them became visible, and each of them was called a private part because its exposure displeases its owner. {And they began to fasten} they began to stick {upon themselves leaves from Paradise} to cover themselves with them. {And Adam disobeyed his Lord and went astray} by eating from the tree.
