Abu al-Rabi' al-'Ataki, Hamid ibn 'Umar, Qutaybah ibn Sa'id, and Abu Kamil narrated to us, all from Hammad ibn Zayd. Abu al-Rabi' said: Hammad narrated to us, from Ayyub, from Abu Qilabah, from Anas, who said: The Messenger of Allah, peace and blessings be upon him, was on one of his journeys, and a black slave boy named Anjashah was driving the camels with song. The Messenger of Allah, peace and blessings be upon him, said to him: "O Anjashah, go slowly with the glass vessels."
