Abu Kulayb Juhani (may Allah be pleased with him) narrates that I came to the Noble Prophet (peace and blessings be upon him) and I said: I have become a Muslim. The Prophet (peace and blessings be upon him) said: Then cast off the hair of disbelief. Another narrator stated that the Prophet (peace and blessings be upon him) said: Shave the hair of disbelief. Another man informed me that the Noble Prophet (peace and blessings be upon him) said to another person: Remove the hair of disbelief and perform circumcision.
