It is narrated from Sayyiduna Mu'adh that the Prophet (peace and blessings be upon him) said: Whoever defends and protects a Muslim behind his back in the presence of a hypocrite who is mentioning his faults, Allah will send an angel on the Day of Resurrection who will protect his flesh from the fire of Hell. And whoever accuses a Muslim of something in order to disgrace him, Allah will stop him on the bridge over Hell until he is freed from what he said.
