It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: The severe wrath of Allah descends upon the person whom a prophet has killed with his own hand in jihad in the way of Allah, and the severe wrath of Allah descends upon the person who calls himself "Shahanshah" (King of Kings); there is no sovereignty except that of Allah.
