Shuraih asked Aishah: "What would the Messenger of Allah ﷺ do as soon as he entered the house?" She replied: " (He would use) the siwak. "

Aishah narrated: "The Prophet of Allah ﷺ would clean his teeth with the Siwak, then he would give me the Siwak in order to wash it. So I would first use it myself, then wash it and return it.

Narrated Aishah, Ummul Muminin: The Messenger of Allah ﷺ said: Ten are the acts according to fitrah (nature): clipping the moustache, letting the beard grow, using the tooth-stick, cutting the nails, washing the finger joints, plucking the hair under the arm-pits, shaving the pubes, and cleansing one's private parts (after easing or urinating) with water. The narrator said: I have forgotten the tenth, but it may have been rinsing the mouth.

Narrated Ammar bin Yasir: The Messenger of Allah ﷺ said: The rinsing of mouth and snuffing up water in the nose are acts that bear the characteristics of fitrah (nature). He then narrated a similar tradition (as reported by Aishah), but he did not mention the words "letting the beard grow". He added the words "circumcision" and "sprinkling water on the private part of the body". He did not mention the words "cleansing oneself after easing". Abu Dawud said: A similar tradition has been reported on the authority of Ibn Abbas. He mentioned only five sunnahs all relating to the head, one of them being parting of the hair; it did not include wearing the beard. Abu Dawud said: The tradition as reported by Hammad has also been transmitted by Talq bin Habib, Mujahid, and Bakr bin Abd Allaah bin al-Muzani as their own statement ( not as a tradition from the Prophet, ﷺ ). They did not mention the words "letting the beard grow". The version transmitted by Muhammad bin Abd Allaah bin Abi Maryam, Abu Salamah, and Abu Hurairah from the Prophet ﷺ mentions the words "letting the beard grow". A similar tradition has been reported by Ibrahim al-Nakha'i. He mentioned the words "wearing the beard and circumcision. "

Narrated Hudhaifah: When the Messenger of Allah ﷺ got up during the night (to pray), he cleansed his mouth with the tooth-stick.

Narrated Aishah, Ummul Muminin: Ablution water and tooth-stick were placed by the side of the Prophet ﷺ. When he got up during the night (for prayer), he relieved himself, then he used the tooth-stick.

Narrated Aishah, Ummul Muminin: The Prophet ﷺ did not get up after sleeping by night or by day without using the tooth-stick before performing ablution.

Narrated Ibn Abbas: I spent a night with the Prophet ﷺ. When he woke up from his sleep (in the latter part of the night for prayer) he came to his ablution water. He took the tooth-stick and used it. He then recited the verse: "Verily in the creation of the heavens and the earth and the alternation of the night and the day are tokens (of His Sovereignty) for men of understanding" (iii-190). He recited these verses up to the end of the chapter or he finished the whole chapter. He then performed ablution and came to the place of prayer. He then said two rak'ahs of prayer. He then lay down on the bed and slept as much as Allaah wished. He then got up and did the same. He then lay down and slept. He then got up and did the same. Every time he used the tooth-stick and offered two rak'ah of prayer. He then offered the prayer known as witr. Abu Dawud said: Fudail on the authority if Husain reported the wording: He then used the tooth-stick and performed ablution while he was reciting the verses: "Verily in the creation of the heaves and the earth. . . " until he finished the chapter.

Narrated Abul Malih: The Prophet ﷺ said: Allah does not accept charity from goods acquired by embezzlement as He does not accept prayer without purification.

Narrated Abu Hurairah: The Messenger of Allah ﷺ said: Allaah, the Exalted, does not accept the prayer of any of you when you are defiled until you performed ablution.
