Hadith record

Hadith.127 - A group of Jews came to the Messenger of Allah (sw) and asked Him about various matters. Among the questions they asked was: ‘Tell us, O’ Muhammad, why these four parts are washed in ablution when they are the cleanest parts of the body?' The Prophet (sw) replied: "When Satan whispered to Adam (as), he approached the tree and looked at it, and thus he lost the brightness of his face. Then he walked towards it—this was the first step taken towards wrongdoing. He reached out with his hand to take from it, and he ate. Consequently, the ornaments and coverings left his body, and he placed his hands on his head and wept. When Allah (swt), Mighty and Majestic, accepted his repentance, He made it obligatory upon him and his descendants to purify these four parts. Thus, Allah (swt) commanded the washing of the face because he had looked at the tree, the washing of the hands up to the elbows because he had used them to take from it, the wiping of the head because he had placed his hand on his head, and the wiping of the feet because he had walked with them towards the wrongdoing (khatee'ah)."
