al-Zuhri ابن شهاب الزهري‎, محمد بن مسلم · The Book of Purification and its Sunnah

"The Messenger of Allah said: 'When anyone of you performs ablution and does it well, then he comes to the mosque for no other purpose than prayer, he does not take one step but Allah will raise him one degree (in status) thereby, and remove one sin from him thereby, until he enters the mosque.'"

The Messenger of Allah said: "Whoever performs ablution and rinses his mouth and nose, his sins will exit through his mouth and nose. When he washes his face, his sins will exit from his face, even from beneath his eyelids. When he washes his hands, his sins will exit from his hands. When he wipes his head, his sins will exit from his head, and even from his ears. When he washes his feet, his sins will exit from his…

The Messenger of Allah said: "None of you should fail to say, when he enters his toilet: 'Allahumma inni a`udhu bika minar-rijsin-najis, al-khabithil-mukhbith, ash-Shaitanir-rajim (O Allah, I seek refuge with You from the filthy and impure, the evil one with evil companions, the accursed Shaitan).'" (Da'if) Another chain with a slightly different wording from Ibn Abi Maryam who mentioned similar, but he did not say in his narration: "Minar-rijsin-najis (From the filthy and the impure)" he only said: "Minal-khabithil-mukhbith, ash-Shaitanir-rajim…

"The Prophet went out to urinate, and 'Umar followed him with water. He said: 'What is this, O 'Umar?' He said: 'Water.' He said: 'I have not been commanded to perform ablution every time I urinate. If I did that it would have become a Sunnah.'"

"The Prophet and his wife would take a bath from one vessel, but neither of them would have a bath with the leftover water of the other." (Daif)

The Prophet and Maimunah took a bath from a single vessel, a large bowl in which they were some traces of dough.

"The Messenger of Allah said: 'When you perform ablution, sprinkle water.'"

"The Prophet, Abu Bakr and 'Umar ate some bread and meat, and they did not perform ablution (after that)."

"Some meat from the shoulder of a sheep was brought to the Messenger of Allah and he ate some of it, then he performed prayer without touching water (for ablution)."

The Messenger of Allah kissed one of his women (i.e., wives), then he went to perform the prayer, and he did not perform ablution. I ('Urwah bin Zubair) said: "That was not anyone but you,' and she smiled."

"The Messenger of Allah would perform ablution, then he would kiss, then he would perform prayer without performing ablution again. And sometimes he did that with me."

"The Messenger of Allah said: 'No ablution (is needed) unless there is an odor or a sound.'"

He asked his sister Umm Habibah, the wife of the Prophet: "Did the Messenger of Allah ever offered prayer in a garment in which he had sexual intercourse?" She said: "Yes, if there was nothing noxious on it."

"I put out some water for the Prophet to take a bath, and he bathe to cleanse himself from impurity following sexual activity. He tilted the vessel with his left hand, pouring water into his right, and washed his hands three times. Then he pourd water over his private parts, then he rubbed his hands on the ground. Then he rinsed his mouth and nose, and washed his face three times, and his forearms three times. Then he poured water…

The Prophet used to go round to all his wives with one bath.

Abu Sa'ib, the freed slave of Hisham bin Zuhrah, told him that he heard Abu Hurairah say: "The Messenger of Allah said: 'No one of you should bathe in standing water when he is sexually impure.'" He (Abu Sa'ib) said: "What should he do, O Abu Hurairah?" He said: "Let him take some out (and pour it over himself)."

She went to the Messenger of Allah and complained to him about bleeding. The Messenger of Allah said: "Rather that is a vein, so look and see when your period comes, then do not perform the prayer. When the period is over, then purify yourself and perform the prayer between one period to the next."
