Abū ʿAbdallāh (Abū Aṣbagh) ʿAbd al-ʿAzīz b. ʿAbdallāh b. Abī Salama al-Mājishūn (d. 164/780-1), a mawlā (client) of the Āl al-Munkadir b. al-Ḥuḍayr al-Taymī in Medina, was, with Mālik b. Anas (d. 179/796), one of the most renowned disciples of Rabīʿa b. Abī ʿAbd al-Raḥmān (called "Rabīʿat al-Raʾy"; d. 136/753). The rivalries between Mālik and al-Mājishūn, mentioned repeatedly in the biographical dictionaries of scholars, were probably what prompted al-Mājishūn to leave Medina and to settle in Baghdad
