It is narrated from Hazrat Imran bin Husain (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) would always encourage giving charity in his addresses and would forbid mutilation. Remember! Mutilation also includes that a person vows to cut off someone's nose, and also that a person vows to perform Hajj on foot. Such a person should take a sacrificial animal along and ride on it.
