CHAPTER: Cleansing With Water After Relieving Oneself.
Narrated Anas bin Malik: The Messenger of Allah صلی اللہ علیہ وسلم entered a park. He was accompanied by a boy who had a jug of water with him. He was the youngest of us. He placed it near the lote-tree. He ( the Prophet, صلی اللہ علیہ وسلم ) relieved himself. He came to us after he had cleansed himself with water.
Narrated Abu Hurairah: The Prophet صلی اللہ علیہ وسلم said: The following verse was revealed in connection with the people of Quba': In it are men who love to be purified (ix. 108). He (Abu Hurairah) said: They used to cleanse themselves with water after easing. So the verse was revealed in connection with them.
