Sayyiduna Imran bin Husayn (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) forbade mutilation, "and part of mutilation is for a man to pierce his nose, and part of mutilation also is for a man to vow that he will perform Hajj on foot. If he does that, let him send a sacrificial offering (hady) and ride."
