It is narrated from Sayyiduna Mu'adh bin Anas al-Juhani (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever protects a believer from a hypocrite who is finding faults with him, Allah Almighty will send down an angel upon him who will protect his flesh from the fire of Hell on the Day of Judgment. And whoever pursues a believer with something blameworthy in order to disgrace him, Allah Almighty will stop him on the bridge over Hell until he withdraws from what he has said.
