"Ali, Al-Miqdad and 'Ammar were talking. 'Ali said: 'I am a man who emits a lot of Madhi but I am too shy to ask the Messenger of Allah (ﷺ) about that because of his daughter's position with me, so let one of you ask him.' He told me that one of them - but I forgot who - asked him, and the Prophet (ﷺ) said: 'That is Madhi. If any one of you notices that, let him wash it off himself and perform Wudu' as for prayer or similar to the Wudu' of prayer.'"

"I sent Al-Miqdad to the Messenger of Allah (ﷺ) to ask him about Madhi, and he said: 'Perform Wudu' and sprinkle water over your private part.'"Abu 'Abdur-Rahman said: Makhramah (one of the narrators) did not hear anything from his father.
"Ali bin Abi Talib sent Al-Miqdad to the Messenger of Allah (ﷺ) to ask him about a man who notices Madhi. The Messenger of Allah (ﷺ) said: 'Let him wash his penis then perform Wudu'.'"
) "For his daughter is (married) to me and I feel too shy to ask him." So he asked the Messenger of Allah (ﷺ) about that and he said: "If any one of you notices that let him sprinkle water on his private parts and perform Wudu' as for prayer."
Chapter 31: The Command To Perform Wudu' After Sleeping
"The Messenger of Allah (ﷺ) said: 'When any one of you gets up after (sleeping) at night, let him not put his hand into the vessel until he has poured water on it two or three times, for none of you knows where his hand spent the night.'"
"I prayed with the Prophet (ﷺ) one night, and I stood on his left, but he made me stand on his right, and he prayed. Then he reclined on his side and took a nap, then the Mu'adhdhin came to him and he prayed, and did not perform Wudu'."
"If anyone of you feels drowsy during his Salah, let him go and take a nap."
Chapter 32: Wudu' After Touching One's Penis
"The Messenger of Allah (ﷺ) said: 'Whoever touches his private part, let him perform Wudu'.'"
"If any one of you touches his private part with his hand, let him perform Wudu'."
"Busrah bint Safwan told me that." 'Urwah sent someone to check that, and she said: "The Messenger of Allah (ﷺ) mentioned what Wudu' is done for, and said: 'Touching the penis.'"
"Whoever touches his penis, he should not perform Salah until he performs Wudu'."Abu 'Abdur-Rahman (An-Nasa'i) said: Hisham bin 'Urwah did not hear this Hadith from his father.
