Banu Qatada, sharifs of Mecca

The Banu Qatada were the emirs of Mecca after the Hawashim. Ibn Khaldun says that they descend from Musa al-Jawn ibn Abd Allah ibn al-Hasan al-Muthanna, and that they were nomadic Bedouins in the valley of Yanbu'. ¹

Abu Aziz ibn Qatada was a counterpart of the Hawashim. When their affair weakened, he inherited it, and took Mecca from their hands through the women's line. He died in 589 AH. ¹

Qatada ibn Idris acquired many mamluks, and his rule extended from the borders of Yemen to Medina, and he had the fortress of Yanbu'. ¹

His descendants then held the office until Abu Numay, who was autocratic in the affairs of Mecca for about fifty years. Then his two sons, Rumaytha and Humayda, governed it. They were its emirs until Ibn Khaldun's time. ¹

A second source is needed: the dates, and a second source other than Ibn Khaldun.
