His son Eli, Sudan, and settled in Basqadi West (now a protected area) in 1444 AH. Dr. Hassan Al-Fatih Qareeb Allah suggests that Abdullah Al-Sharif was the first pioneer of the Shadhiliyya in Sudan, as mentioned by Ibn Dhaif Allah. As for the Sammaniyya, Sheikh Ahmed Al-Tayeb Al-Bashir Al-Jamou'i spread its teachings in 1971 (1391 AH). He received his education in Medina from the founder of the first order, Sheikh Muhammad Abdul Karim Al-Samman. The Sammaniyya was a manifestation of the religious reform that swept through the southern provinces of the state. The Sammani family was known for its knowledge, piety, and literature. Sheikh Ahmed Al-Tayeb (Al-Oshmaniyya) took knowledge from his grandfather Sheikh Muhammad Walad Burur, traveled to the mosque of Sheikh Al-Azazi in Umm Talha in Al-Jazeera, then headed to Medina and stayed there for seven years. Upon his return, he used to treat people by praying for their blessings and healing. It is narrated that he treated the brother of Sheikh Al-Nasir Walad Muhammad Abi Al-Kailak. The Sammaniyya order found acceptance and approval among some Arab tribes in Sudan, such as the Jamou'iyya, Al-Halawin, and Al-Ya'qubab. Sufism spread greatly in Sudan, and its effects were evident in people's lives, their worship, and their religious conduct. Sufi terminology and phrases, indicative of the deep and strong Sufi reality among Sudanese, prevailed in their atmosphere. A number of books with Sufi content spread, such as the books of Abdul Wahab Al-Sha'rani, including "Al-Tabaqat Al-Kubra" and "Lata'if Al-Munan wa Al-Akhlaq fi Bayan Al-Tuhadduth bi Ni'mat Allah 'ala Al-Ilaq." Among the books of the nationalists on Sufism is "Al-Tabaqat" by Walad Dhaif Allah, in which he translates the biographies of a number of scholars, jurists, Sufis, and poets. It abounds with talk of the miracles of saints and the extraordinary nature of their actions. Professor Mahmoud Abdullah Baratt believes that the book lacks clarity, methodology, and a correct comprehensive vision. However, in our opinion, the book is a purely Sudanese effort by a national author expressing what prevailed in Sudanese society.
