Abu al-Hasan as-Said al-Mutadid (; abū al-ḥasan al-mu`taḍid bi-llah as-sa`īd ben al-mā'mūn; died 1248) was an Almohad caliph who reigned from 1242 until his death. He was a son of Idris al-Ma'mun.
Life He succeeded his brother Abd al-Wahid II in a period in which the Almohads controlled only parts of present-day Morocco. During his reign, he tried to recover Meknes from the Marinids and Tlemcen from the Zayyanids. As-Said was able to obtain a contingent from the Marinids who made a nominal submission to him, but was killed by the Zayyanids in the Battle of Oujda after which his head was taken and ordered to be shown to his mother.Histoire des Beni Zeiyan, rois de Tlemcen, par Abou-Abd'Allah-Mohammed ibn-Abd'el-Djelyl et Tenessy, ouvrage trad. par ...

The Marinids then took the opportunity to conquer Fes, reducing the Almohads’ effective control to the Marrakesh area.
