Musnad Ahmad 980:19

Wahb ibn Jarir narrated to us, Shu'bah narrated to us, from al-A'mash, from Abu 'Amr al-Shaybani, from Abu Mas'ud, that a man gave a she-camel with a nose-rein in charity for the sake of Allah. The Messenger of Allah (peace and blessings of Allah be upon him) said: "You shall certainly be brought, or she shall certainly be brought, with seven hundred she-camels with nose-reins."
