Al-Mubarrad (المبرد) (al-Mobarrad), or Abū al-‘Abbās Muḥammad ibn Yazīd, was a native of Baṣrah. He was a philologist, biographer and a leading grammarian of the School of Basra, a rival to the School of Kufa. In 860 he was called to the court of the Abbasid caliph al-Mutawakkil at Samarra. When the caliph was killed the following year, he went to Baghdād, and taught there until his death.
