Abu Hafs expanded the biography, and his path was through Ifrīqiyya, according to his predecessors, with love for scholars. Some of them he dispersed, others he kept. They spread their secrets, and they were his servants, his close associates, and his beloved. People loved him and inclined towards him. He learned from the intelligent among his father's people and was involved in collecting funds that his father had not taken. The blood spilled over to others. Then Ya'qūb Muhammad bin 'Abd al-Karīm took over in Matmāta, and he was a merchant. He arrested its previous governor, who was Sheikh Abu Muhammad Bu Nasr bin Sheikh Abu Hafs bin 'Abd al-Mu'min. This was in the year 595 AH. Yahya bin al-Nuhāf took over Mayūra, Tripoli, Tunis, and other places. It so happened that some of them killed each other because of what Ibn al-Nuhāf did to them, changing the governors and torturing them. We have already mentioned the history of that. When al-Nāṣir, Ya'qūb's son, heard about the actions of the people of Ifrīqiyya, the Burgh, and Abu 'Abd al-Karīm, he became angry and moved towards them. He used to reach Mayūra and other places until al-Nāṣir reached Bijāya. His men reached him and informed him of his movements and wealth towards Mahdia, to be under the control of his cousin 'Ali bin al-Ghāzī. He left Tunis and headed to Qayrawān, then to Qabṣa. He met with the Arabs, took their hostages, and made them swear allegiance to him for service. Then he came to the land of Tafarār and found the soldiers killing many of its people, plundering their wealth, and setting fire to some of their homes. This was because he had heard of their disobedience. Then he moved to Matmāta and heard that al-Nāṣir had suffered a setback on the road to Bu Sab', and his followers had been taken on the road to Qabṣa. He moved to Jabal Damr, whatever he could gather. Al-Nāṣir reached Qabṣa, followed by news from Yahya informing him of his move to Jabal Damr. He returned to Tunis and appointed Ḥajīj from the Muwaḥḥidūn to govern the lands. On his return, he engaged in battle with Sheikh al-Muqaddas Abu Muhammad 'Abd al-Wāḥid bin Abu Hafs, and sent a large army with him to confront Yahya al-Abrāz, who had fled to the desert. The scribe informed him of this. They were put to the test in battle. The battle of Abu Muhammad 'Abd al-Wāḥid, known as Matjar bi-Sanrās, took place. Many of Yahya's supporters were there, and a small group of Burjiya. The departure of his family and children was about five parasangs away. If it hadn't been for that, they would have been captured. Sheikh Abu Muhammad, in front of Sayyid Abu Zayd, was struck by the one assigned to him with blows intended to kill him. This hastened his demise. He rescued a group of Muwaḥḥidūn who were with him and took his black banner. The Muwaḥḥidūn surrounded all his army and the wealth and camels they had, which they could not count. Sheikh Abu Muhammad returned with all of this to al-Nāṣir, who was besieging Mahdia, where 'Ayy bin al-Ghāzī was in Mayūra. Al-Amīn, who was in charge of Sheikh Abu Zayd's affairs, rode on a camel, carrying the black banner, towards Mahdia. The defeat occurred on the thirteenth of Rabī' al-Awwal in the year 702 AH. Hammād al-Māti', known for his armor, was in a piece of land between Ibisītis and 'Ayr. Muhammad satirized Yahya and mentioned the defeat.
