The Darqawi-Alawi branch of the Shadili tariqa also established itself in Damascus and the Levant through Sheikh Muhammad al-Hashimi al-Tilmisani, the son of an Algerian qadi, who migrated to Damascus along with his spiritual guide Ibn Yallis. After the death of Ibn Yallis, Hashimi was authorized by Sheikh Ahmad al-'Alawi (see above Martin Lings), during a visit to Damascus in the early 1920s, and was made his deputy in Damascus. A biography of his life was published in English as "Shaykh Muhammad al-Hashimi: His Life and Works".
