Concerning Allah's statement,

فَأَكَلَا مِنْهَا فَبَدَتْ لَهُمَا سَوْآتُهُمَا ...

Then they both ate of the tree, and so their private parts became manifest to them,

Ibn Abi Hatim recorded that Ubayy bin Ka`b said that the Messenger of Allah said,

إِنَّ اللهَ خَلَقَ آدَمَ رَجُلًا طُوَالًا كَثِيرَ شَعْرِ الرَّأْسِ، كَأَنَّهُ نَخْلَةُ سَحُوقٍ،فَلَمَّا ذَاقَ الشَّجَرَةَ سَقَطَ عَنْهُ لِبَاسُهُ، فَأَوَّلُ مَا بَدَا مِنْهُ عَوْرَتُهُ، فَلَمَّا نَظَرَ إِلَى عَوْرَتِهِ جَعَلَ يَشْتَدُّ فِي الْجَنَّةِ، فَأَخَذَتْ شَعْرَهُ شَجَرَةٌ فَنَازَعَهَا، فَنَادَاهُ الرَّحْمَنُ: يَا آدَمُ مِنِّي تَفِرُّ، فَلَمَّا سَمِعَ كَلَامَ الرَّحْمَنِ قَالَ: يَا رَبِّ لَا، وَلَكِنِ اسْتِحْيَاءً، أَرَأَيْتَ إِنْ تُبْتُ وَرَجَعْتُ أَعَائِدِي إِلَى الْجَنَّةِ؟ قَالَ: نَعَم

Verily, Allah created Adam as a tall man with an abundance of hair on his head. He looked like a clothed palm tree. Then, when he tasted (the fruit of) the tree, his clothes fell off of him. The first thing that became exposed was his private parts. So when he noticed his nakedness, he tried to run back into Paradise. However, in the process a tree caught hold of his hair (i.e. his hair was tangled in a tree), so he ripped his hair out. Then, the Most Beneficent called out to him saying, "O Adam, are you fleeing from me!''

When he heard the Words of the Most Beneficent, he said, "No my Lord, but I am ashamed. If I repent and recant would You let me return to Paradise!''

Allah replied, "Yes.''

This is the meaning of Allah's statement,

فَتَلَقَّى ءَادَمُ مِن رَّبِّهِ كَلِمَاتٍ فَتَابَ عَلَيْهِ

Then Adam received from his Lord Words. And his Lord pardoned him. (2:37)

However, this narration has a break in the chain of transmission between Al-Hasan and Ubayy bin Ka`b. Al-Hasan did not hear this Hadith from Ubayy.

It is questionable as to whether this narration can be correctly attributed to the Prophet.

Allah said,

... وَطَفِقَا يَخْصِفَانِ عَلَيْهِمَا مِن وَرَقِ الْجَنَّةِ ...

And they began to cover themselves with the leaves of the Paradise for their covering.

Mujahid said,

"They patched the leaves on themselves in the form of a garment.''

Qatadah and As-Suddi both said the same.

Concerning Allah's statement,

... وَعَصَى آدَمُ رَبَّهُ فَغَوَى ﴿١٢١﴾

ثُمَّ اجْتَبَاهُ رَبُّهُ فَتَابَ عَلَيْهِ وَهَدَى ﴿١٢٢﴾

Thus Adam disobeyed his Lord, so he went astray. Then his Lord chose him, and turned to him with forgiveness, and gave him guidance.
