 In addition to Muhammad, Onneca bore Abdullah two daughters: al-Baha 'and Fatima the Younger. Abdullah became emir in 888, and Onneca's son Muhammad was named heir to the throne. However, Muhammad was assassinated by his younger half-brother al-Mutarrif on 28 January 891. There is disagreement among historians as to whether al-Mutarrif acted on his own or at the instigation of his father Abdullah. Al-Mutarrif himself was beheaded in 895 under orders of his father. As a result, Muhammad's son Abd-ar-Rahman, who was born three weeks prior to his father's assassination, was the one who succeeded his grandfather Abdullah as emir of Córdoba. Known in the West as Abd-ar-Rahman III, he later elevated himself to the position of caliph.
