ʻAbd al-Salām ibn Mashīsh al-ʻAlamī (Arabic: عبد السلام بن مشيش العلمي) (b. ?–1227), was a Moroccan Sufi saint who lived during the reign of the Almohad Caliphate.
Virtually nothing is known about him except that he was assassinated in 1227/1228 by the anti-Almohad rebel ibn Abi Tawajin.[1]
His genealogy was traced through several ancestors—some of them with typically Berber names—all the way to the Prophet of Islam, Muhammad. It is said that he was born to the Banu Arus tribe in the neighbourhood of the Jabal al-'Alam, and that at the age of 16 he travelled to the east to study. On his return, in Béjaïa, he followed the instructions of the Andalusian mystic Abu Madyan. He came back to stay in his native country, where he withdrew to the mountain to live an edifying life as an ascetic. He was the murshid (spiritual guide) of Al-Shadhili, and his only disciple.
