(17) باب فِي نَتْفِ الشَّيْبِ
'Amr b. Shu'aib, on his father's authority, told that his grandfather reported the Messenger of Allah (ﷺ) said:
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.
