From here, the great Islamic role played by Sulaiman Solon, which we prefer to accept the saying that he ruled in the period 848-880 AH / 1445-1476 AD, and not other accounts, is no different from the role played by Amara Donges in 910 AH / 1505 AD, in terms of activating the Islamic call and working to spread Islam among pagan tribes, as well as working to deepen Islamic concepts. From here, that sultanate emerged as an Arab Islamic power and a civilizational principality in the sky of Arab Islamic life in the ninth Hijri century, the fifteenth AD century, not the seventeenth or sixth century as some research has tried to portray.

This is because the Arab Islamic waves were advancing in the fourteenth and fifteenth centuries into the sixteenth or seventeenth century, as those who brought oral accounts from some men and scholars of Darfur tried to portray. From here, that land became an Islamic land, as educated and deeply Islamic cultured elements arrived from Borno and Bagirmi. In fact, the encouragement of commercial movement was one of the fundamental reasons that motivated scholars to come to Darfur, accompanying the arriving caravans. From here, people began to enter the religion of Islam in large numbers due to their connection with trade, merchants, scholars, imams, religious men, and jurists.

Arnold Thomas mentions in his book "The Call to Islam" that Islam did not establish its roots, was not widely preached, and did not become a dense Islamic population in the lands from Kordofan in the east to Lake Chad in the west, such as Darfur, Wadai, and Bagirmi, except in the eighth Hijri century, the sixteenth AD century.

Indeed, to confirm this Islamic spirit whose image has become clear, the Sultans of Fuzz attributed themselves to the noble Arab House, to the lineage of the Abbasids.
