As-salamu Žalaykum, Is there anything specific that you would like to know? Sayyidi al-Imam al-Kabir Muhammad al-Sanusi (radiya'Allahu Žanhu) was the senior khalifah of the known Qutb Sayyidi Ahmad bin Idris, radiya'Allahu Žanh. As for being ghayr muqalled, like Sayyidi Ahmad bin Idris, the Imam was opposed to taŽassub in the mathaheb (and they were both criticized by Shaykh Ulaysh), as I have explained in another thread on this forum. This is following in the footsteps of Shaykh al-Akbar, similar to how Hafith Ahmad bin as-Siddiq al-Ghumari would do in the 20th century. Like the Idrisiyya (which it is a part of, as opposed to a seperate Tariqah) it is "based" on the Shadhiliyya. The Sanusi path's core is Ittiba' of the Sunnah and salat Žala an-nabi, salla Llahu Žalayhi wa alihi wa sallam. wassalam
