Narrated Ammar b. Yasir:

The Messenger of Allaah ( sal Allaahu alayhi wa sallam ) 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 b. Habib , Mujahid, and Bakr b. 'Abd Allaah b. al-Muzani as their own statement ( not as a tradition from the Prophet, sal Allaahu alayhi wa sallam ).They did not mention the words "letting the beard grow". The version transmitted by Muhammad b. Abd Allaah b. Abi Maryam, Abu Salamah, and Abu Hurairah from the Prophet ( sal Allaahu alayhi wa sallam ) 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."
