Sunan Abi Dawud — The Book Of The Prayer For Rain (Kitab al-Istisqa') — Hadith No: 1188

Abu Hurairah reported:The prayer (in congregation) began and people stood in their rows. The Messenger of Allah (May peace be upon him) came out (from his residence). When he stood at his proper place he recalled that he did not take a bath. He then said to the people: (Remain standing) at your places. Then he returned to his house and came out upon us after taking a bath while the drops of water were coming down from his head. We were standing in the rows (of prayer). This is the version of Ibn Harb. ‘Ayyash reported in his version: we kept on waiting for him while we were standing until he came upon us after he had taken a bath

Narrated Aisha, Ummul Mu'minin: If you want, I can certainly show you the marks of the hand of the Messenger of Allah (ﷺ) on the wall where he took a bath because of sexual defilement

Narrated Aisha, Ummul Mu'minin: The Prophet (ﷺ) was asked about a person who found moisture (on his body or clothes) but did not remember the sexual dream. He replied: He should take a bath. He was asked about a person who remembered that he had a sexual dream but did not find moisture. He replied: Bath is not necessary for him. Umm Salamah then asked: Is washing necessary for a woman if she sees that (in her dream)? He replied: Yes. Woman are counterpart of men

Aishah said; When the Messenger of Allah (May peace be upon him) intended to take a bath because of sexual defilement, he would begin with his hands and wash them. Then he would wash the joints of his limbs and pour water upon him when he cleansed both his (hands), he would rub them on the wall (to make them perfectly clean with the dust). Then he would perform ablution and pour water over his head
