Abd al-Salam ibn Mashish al-Hasani (d. c. 625/1228; sources give dates between 622 and 626 AH) was a Moroccan Sufi of Sharifian Hasanid descent who lived in ascetic seclusion atop Jabal al-Alam in the Rif mountains. Though he founded no order and refused to gather disciples, the ijaza he transmitted trained Abu'l-Hasan al-Shadhili, making him the spiritual fountainhead of the Shadhiliyya. His whitewashed tomb on the summit of Jabal al-Alam near Tetouan/Chefchaouen is the site of a major annual moussem; he is reported to have been killed by the anti-Almohad rebel Ibn Abi Tawajin. There is no dispute over the burial site; only his death year (622/623/625/626) varies among sources. (Source: TDV Encyclopedia of Islam "Abdüsselâm b.
