al-Hasan al-Basri الحسن البصري · The Book of Adornment

"The Messenger of Allah said: 'Let the beard grow and trim the mustache.'"

"I heard the Messenger of Allah say: 'Whoever does not take from his mustache, he is not one of us.'"

The Prophet saw a boy, part of whose head had been shaven and part had been left. He forbade that and said: "Shave all of it, or leave all of it."

"The pommel of the sword of the Messenger of Allah was of silver."
