He was succeeded by his son, al-Mahdi, who was the third Caliph. The Abbasids were restless and hesitant.

He dismissed Musa and appointed Abd Allah ibn Muhammad in the year 169 AH. Salman of Syria.

Then he dismissed him and appointed Ubayd Allah ibn Ali. He dismissed this one and appointed Isa ibn Yahya in the year 170 AH.

In this year, Ubayd Allah was dismissed and Wadhih, a freedman of al-Jafar, was appointed. After a period, he was replaced by Kundur ibn Dawud ibn Yazid al-Ruyayni, who was the cousin of the Caliph. In the year 171 AH, He replaced him with Yahya ibn Dawud, nicknamed Abu Salih, from Khurasan. His father was a Turk. He was the most severe and imposing of men, the quickest to shed blood, and the most severe in punishment. He prohibited the closing of roads at night and the closing of shops until They were covered with reeds and dogs. He also prevented the guards of the baths from sitting in them and said, "Whoever loses something must pay for it." A man would enter The baths. Things were going on like this, except for the baths. He would take off his clothes and say, "O Abu Salih, guard my clothes."

His reign lasted for a period. In the year 172 AH, Abu Salih was dismissed and Salim ibn Sawada al-Qurashi was appointed. In the year 173 AH, Al-Mahdi dismissed him and appointed Ibrahim ibn Salih ibn Ali ibn Abd Allah ibn Abbas. In Muharram of the year 174 AH, He dismissed him and appointed Musa ibn Sa'd ibn al-Zubayr, from the people of Mosul. When he arrived in Egypt, he took three thousand dinars from Ibrahim and those with him, then sent him to Baghdad. Musa intensified the collection of taxes and doubled the amount per feddan. He imposed a tax on Shops and on the ferries, which caused the people hardship and dislike.

They opposed him, and Qays and al-Ghazzi revolted. They wrote to the people of Fustat, and they agreed. He sent Bakhsh To fight Dahiya in Upper Egypt and marched out with the army of Egypt to fight the people of the Hawf. When they met, the people of Egypt were defeated.

He was killed in Shawwal of the year 175 AH, without anyone speaking. His reign lasted ten months, and he was a tyrannical oppressor. Al-Mahdi appointed Usama ibn Umar as acting governor until he sent for al-Hawari and ordered Dahiya to be apprehended, as the people had written to him and invited him. So al-Fadl sent his armies to him, and he had brought reinforcements from Syria. Dahiya's cavalry was routed, and he was captured.

He said, "I am the most deserving of the governorship of Egypt, for I fought in the matter of Dahiya, and others have already paid for it." It is said that He regretted killing Dahiya. In that year, al-Fadl built the mosque, and people used to gather there.
