Maliks Muwatta Book 051, Hadith Number 002.

Section : The Sunna on Hair.

Yahya related to me from Malik from Ibn Shihab that Humay ibn Abd ar-Rahman ibn Awf heard Muawiya ibn Abi Sufyan say from the mimbar in the year that he performed the hajj, holding a lock of hair (i.e. a hairpiece) which he took from one of his guards, "People of Madina! Where are your learned men? I heard the Messenger of Allah, may Allah bless him and grant him peace, forbid the like of this, saying, 'The Banu Israil were destroyed when their women started to use this.'"
