It is narrated from Sayyiduna Bilal bin al-Harith (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The (complete) Muslim is the one from whose tongue and hand (harm) the other Muslims are safe."

Al-Harith bin Bilal bin al-Harith al-Muzani narrates from his father that he said: "O Messenger of Allah! Is cancelling the Hajj (by converting it into Umrah) specific to us alone, or is it general for all people?" He (peace and blessings be upon him) said: "Rather, it was specific to us alone (that is, to this group of Companions)."

It is narrated from Sayyiduna Bilal bin al-Harith al-Muzani (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) gave judgment on the basis of one witness together with the oath (of the claimant).
