The Prophet (ﷺ) as saying: The inborn characteristics of man are five. Another version says: Five things are of the inborn characteristics of man: circumcision, shaving the pubes, plucking out hair under the armpit, paring the nails and clipping the moustaches.

The Messenger of Allah (ﷺ) commanded to clip the moustaches and grow the beard long.

The Messenger of Allah (ﷺ) fixed forty days to shave the pubes, paring the nails, clipping the moustaches, and plucking the hair under the armpit.

Abu Dawud said: Ja'far b. Sulaiman transmitted it from Abu 'Imran on the authority of Anas. In this version he did not mention the Prophet (ﷺ). He said: Forty days were fixed for us. This is a more correct version.

We used to grow beard long except during the Hajj or 'Umrah.

Abu Dawud said: Istihdad means to shave the pubes.

Do not pluck out grey hair. If any believer grows a grey hair in Islam, he will have light on the Day of Resurrection. (This is Sufyan's version). Yahya's version says: Allah will record on his behalf a good deed for it, and will blot out a sin for it.

The Prophet (ﷺ) as saying: Jews and Christians do not dye (their beards), so act differently from them.

Abu Quhafah was brought on the day of the conquest of Mecca with head and beard while like hyssop. The Messenger of Allah (ﷺ) said: Change this something, but avoid black.

The Prophet (ﷺ) said: The best things with which grey hair are changed are henna and katam.

I went with my father to the Prophet (ﷺ). He had locks hanging down as far as the lobes of the ears stained with henna, and he was wearing two green garments.

My father said to him (the Prophet): Show me what is on your back, for I am a physician. He (the Prophet) said: You are only a soother. Its physician is He Who has created it.

I and my father came to the Prophet (ﷺ). He said to a man or to my father: Who is this? He replied: He is my son. He said: Do not commit a crime on him. He had stained his beard with henna.

He did not dye his hair, but Abu Bakr and 'Umar dyed their hair.

The Prophet (ﷺ) used to wear tanned leather sandals and dye his beard yellow with wars and saffron, and Ibn 'Umar used to do that too.

When a man who had dyed himself with henna passed by the Prophet (ﷺ), he said: How fine this is! When another man who had dyed himself with henna and katam passed by, he said: This is better than that. Then another man who had dyed himself with yellow dye, passed by, he said: This is better than all that.

The Prophet (ﷺ) said: At the end of time there will be people who will use this black dye like the crops of doves who will not experience the fragrance of Paradise.

When the Messenger of Allah (ﷺ) went on a journey, the last member of his family he saw was Fatimah, and the first he visited on his return was Fatimah. Once when he returned from an expedition she had hung up a hair-cloth, or a curtain, at her door, and adorned al-Hasan and al-Husayn with silver bracelets. So when he arrived, he did not enter. Thinking that he had been prevented from entering by what he had seen, she tore down the curtain, unfastened the bracelets from the boys and cut them off.

They went weeping to the Messenger of Allah (ﷺ), and when he had taken them from them, he said: Take this to so and so's family. Thawban. In Medina, these are my family, and I did not like them to enjoy their good things in the present life. Buy Fatimah a necklace or asb, Thawban, and two ivory bracelets.
