Musnad Ahmad 33:1110

Husayn narrated to us, Abu Uways narrated to us, Sharhabil ibn Sa’d al-Ansari, the freed slave of Banu Khatma, narrated to us, from Jabir ibn Abdullah, from the Prophet, peace and blessings of Allah be upon him, who said: "For one of you to restrain his hand from the pebbles is better for him than a hundred she-camels, all of which have black pupils. But if one of you is overcome by the devil, then let him perform one single sweep."
