It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Among the sacrificial camels, the one-eyed and the emaciated animal are not permissible; and beware of the mustalahah (an animal with a healed-over wound)."
