Muslim bin Ibrahim al-Azdy مسلم بن إبراهيم الأزدي الفراهيدي · Combing the Hair (Kitab Al-Tarajjul)

Karimah, daughter of Hammam, told that a woman came to Aisha (Allah be pleased with her) and asked her about dyeing with henna. She replied: There is no harm, but I do not like it. My beloved, the Messenger of Allah (ﷺ), disliked its odour. Abu Dawud said: She meant the colour of hair of the head.

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