Musnad Abu Ya'la al-Mawsili 150:249

Nasr ibn Ali al-Jahdhami narrated to us, Ghibta Umm Amr al-Mujashi’iyya narrated to me, she said: My paternal aunt narrated to me, from my grandmother, from Aisha, she said: I asked her about the *wasila* (the woman who adds hair extensions). She said: The Messenger of Allah (may Allah bless him and grant him peace) cursed the *wasila* (the woman who adds hair extensions) and the *mustawsila* (the woman who asks for hair extensions to be added).
