Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: The Prophet Muhammad (peace and blessings be upon him) sent Sayyiduna Aslami (may Allah be pleased with him) and sent with him eighteen sacrificial camels. He (Aslami) asked: O Messenger of Allah (peace and blessings be upon him)! What is your opinion, if any of these animals becomes unable to travel (what should I do)? The Prophet Muhammad (peace and blessings be upon him) said: Sacrifice it, then dye its shoes (i.e., the shoes that are hung around its neck as a garland) in its blood and mark its side with them. Do not eat from it yourself, nor should any of your companions eat its meat.
