Aishah narrated that the Messenger of Allah (s.a.w) said:
Six are cursed, being cursed by Allah and by every Prophet that came: The one who adds to Allah's Book, the one who denies Allah's Qadar, the one who rules with tyranny by which he honors whom Allah has debased, and he dishonors whom Allah has honored, and the one who legalizes what Allah forbade, and the one from my family who legalizes what Allah forbade, and the abandoner of my Sunnah.
