Ali ibn Abi Talib · The Book of Purification and its Sunnah

"Whenever the Messenger of Allah got up for prayer at night to pray Tahajjud (night optional prayer), he would clean his mouth with the tooth stick."

"Whenever the Messenger of Allah entered the toilet, he would say: 'A'udhu Billahi minal-khubthi wa'l-khaba'ith (I seek refuge with Allah from male and female devils).'"

The Messenger of Allah came to the garbage dump of some people and he urinated on it standing up.

"If anyone tells you that the Messenger of Allah urinated while standing, do not believe him, for I (always) saw him urinating while sitting down."

"I went for Hajj with the Prophet and he went far away to relieve himself."

"The Messenger of Allah said: 'Most of the torment of the grave is because of urine.'"

"A man passed by the Prophet while he was urinating, and greeted him with the Salam, but he did not return the greeting. While he finished, he struck the ground with his palms and did dry ablution (Tayammum), then he returned the greeting."

"The Messenger of Allah said: 'If a dog licks the vessel of anyone of you, let him wash it seven times.'"

"The Messager of Allah and I used to take bath from a single vessel."

On the night of the Jinn the Messenger of Allah said to Ibn Mas'ud: "Do you have water?" He said: "No, only some Nabidh in a large water skin." The Messenger of Allah said: "Good dates and pure water." (i.e. there is no harm from the mixing of the two.) Pour it for me." He said: "So I performed ablution with it."

The Prophet said: "There is no prayer for one who does not have ablution, and there is no ablution for one who does not mention the Name of Allah (before it). There is no prayer for one who does not send blessing, (Salat) upon the Prophet, and there is no prayer for one who does not love the Ansar." (Da'if) Another chain with similar wording.

'Sniff up water into the nostrils thoroughly, two or three times.'"

"The Messenger of Allah used to perform ablution washing each part three times."

"The Messenger of Allah performed ablution and wiped his head twice."

"May my ears be made deaf, if I did not hear the messenger of Allah saying: 'Perform ablution after (eating) that which has been changed by fire.'"

The Prophet said: "Three days." I think he said, "And three nights during which the traveler may wipe over his leather socks."

"I heard Ibn 'Abbas saying that a man was injured in the head at the time of the Messenger of Allah, then he had a wet dream. He was told to have a bath, so he took the bath, became rigid and stiff, and died. News of that reached the Messenger of Allah and he said: 'They have killed him, may Allah kill them! Is not the cure for a lack of knowledge to ask questions?'"'Ata' said: "We heard that…

"The Messenger of Allah used to have a bath to cleanse himself from sexual impurity, then he would warm himself with me before I had the bath."
