Narrated Mu'adh ibn Anas: The Prophet (ﷺ) said: If anyone guards a believer from a hypocrite, Allah will send an angel who will guard his flesh on the Day of Resurrection from the fire of Jahannam; but if anyone attacks a Muslim saying something by which he wishes to disgrace him, he will be restrained by Allah on the bridge over Jahannam till he is acquitted of what he said
