It is narrated from Hazrat Abu Bakrah (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) say: Whoever honors the king appointed by Allah in this world, Allah will honor him on the Day of Resurrection, and whoever humiliates the king appointed by Allah in this world, Allah will disgrace him on the Day of Resurrection.
