Muhammad ibn al-Muthanna and Ibn Bashshar narrated to us, both saying: Muhammad ibn Ja'far narrated to us, from Shu'bah, from Muharib ibn Dithar, who said: I heard Ibn 'Umar saying: "The Messenger of Allah, peace and blessings be upon him, forbade [the use of] al-hantam, al-dubba', and al-muzaffat." He said: I heard him [say this] more than once.
