ibn Isa ibn Musa ibn Shabrit on 15 March 916. Abd al-Malik then had Asbag ibn Isa and Abd al-Malik ibn Isa, the brothers of Zakariyya, killed. His own brother Amrus was next to challenge him and Abd al-Malik ibn Muhammad was captured and strangled on 25 December 918. Amrus ibn Muhammad had been given Monzón by his brother in 914, but was rejected by the residents, who invited Muhammad ibn Lubb al-Qasawi to replace him. He took Huesca from his brother in 918, but was again rejected and was forced out within weeks. Amrus went to Barbastro and Alquézar, asking Abd-ar-Rahman III to appoint him governor there. He then enlisted the help of Sancho I of Pamplona and Bernard I Unifred of Ribagorza to reduce Monzón. He subsequently fought against his brother Furtun, the Banu Qasi, and the Banu Tujib, taking and ransoming several important hostages, but he found himself being captured and ransomed multiple times as well. He submitted to the Caliph in 933/4 and died 6 June 935. Furtun ibn Muhammad was nominated in Huesca in place of his brother Amrus. In 931/2 he signed a pact with Muhammad ibn Hasim, rebel leader of the Banu Tujib, and in response Abd ar-Rahman punished Huesca by imprisoning many men. Huesca responded by expelling Furtun in 933. He initially fled to Las Peñas de San Miguel y Aman, but then went to Córdoba and humbled himself before the Caliph and was restored to Huesca in 936/7. However, at the Battle of Simancas he withheld his troops from the fight, and he was hunted down near Calatayud by Salama ibn Ahmad ibn Salama, taken to Córdoba and crucified in front of its Al-Qasr. Yahya ibn Muhammad received Huesca when Furtun fled in 933 and governed Mérida from 935. However, he fell under suspicion and was imprisoned. Following Furtun's fall he was returned to favor and given Barbastro. He died there 20 December 951. He was succeeded in Barbastro by his brother Lubb ibn Muhammad, who died suddenly at Córdoba in December 955. Other sources report a brief interlude by Walid ibn Muhammad. Musa Aznar ibn Muhammad was given Lleida, and in 940, Huesca. He married Dadildis, daughter of Jimeno Garcés of Pamplona, dying 18 December 954. He was followed in Huesca by a son Abd al-Malik ibn Musa, who was later forced to share Huesca with his cousin, Yahya ibn
