Ibn ‘Abbas said the Prophet liked to do the same as the People of the Book in matters about which he had received no command. The People of the Book used to let their hair hang down and the polytheists used to part their hair, so the Prophet let his forelock hang down, but afterwards he parted it.
(Bukhari and Muslim.)
Jabir told that when Abu Quhafa (Abu Bakr’s father) was brought on the day of the Conquest of Mecca with his head and beard white like hyssop, the Prophet said, “Change this with something, but avoid black.”
Muslim transmitted it.
Nafi‘ quoted Ibn ‘Umar as saying he had heard the Prophet forbidding qaza'. Nafi' was asked what qaza’ was and replied that it was having part of a boy’s head shaved arid leaving part unshaven.
(Bukhari and Muslim.) Some made the explanation a part of the tradition.
