Muhammad bin 'Abd ar-Rahman bin 'Obayd Allah, known as Muhammad III (Arabic: محمد الثالث) was an Umayyad Caliph of Cordoba in Al-Andalus (Moorish Iberia).
Muhammad III ruled after the death of Abd ar-Rahman V from 1024 to 1025[2] but the people of Córdoba revolted against him and fearing the march of Yahya ibn Ali ibn Hammud al-Mu'tali, he was forced to flee the city.[3] It is believed that he died after being poisoned when he was 50 years old. He was also the father of the famous poet Wallada bint al-Mustakfi, whom he had with an Iberian Christian slave.[4]
