Abdalqadir as-Sufi (born Ian Stewart Dallas; 1930 Ayr – 1 August 2021 Cape Town) was a Scottish Muslim leader and author.

He was Shaykh of Instruction, leader of the Darqawi-Shadhili-Qadiri Tariqa, founder of the Murabitun World Movement and author of numerous books on Islam, Sufism and political theory.

[4] He worked at the BBC through the mid-1960s; among his other adaptations were film or theatrical versions of Charlotte Brontë's Jane Eyre, William Makepeace Thackeray's Vanity Fair, Arthur Rimbaud's A Season in Hell, Mikhail Lermontov's A Hero of Our Time, and Eugene O'Neill's Strange Interlude.

[6][11] As-Sufi converted to Islam in 1967 in Fes, Morocco as Abdalqadir, witnessed by Abdalkarim Daudi, the Imam Khatib of the Qarawiyyin Mosque, and Alal al-Fasi.

[16] Abdalqadir as-Sufi taught that suicide terrorism is forbidden under Islamic law, that its psychological pattern stems from nihilism,[17] and that it "draws attention away from the fact that capitalism has failed."
