It is narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) that Sayyiduna Uthman bin Maz'un (may Allah be pleased with him) wished to adopt seclusion, but the Prophet (peace and blessings of Allah be upon him) did not permit him to do so. If the Prophet (peace and blessings of Allah be upon him) had permitted him in this matter, then we too would have at least castrated ourselves.
