I bolded some things I think would help. I need one more brainliest to level up - it would be appreciated!

Islamic political and aesthetic influences on African societies remain difficult to assess. In some capital cities, such as Ghana and Gao, the presence of Muslim merchants resulted in the establishment of mosques. The Malian king Mansa Musa (r. 1312–37) brought back from a pilgrimage to Mecca the architect al-Sahili, who is often credited with the creation of the Sudano-Sahelian building style. Musa’s brother, Mansa Sulaiman, followed his path and encouraged the building of mosques, as well as the development of Islamic learning. Islam brought to Africa the art of writing and new techniques of weighting. The city of Timbuktu, for instance, flourished as a commercial and intellectual center, seemingly undisturbed by various upheavals. Timbuktu began as a Tuareg settlement, was soon integrated into the Mali empire, then was reclaimed by the Tuareg, and finally incorporated into the Songhai empire. In the sixteenth century, the majority of Muslim scholars in Timbuktu were of Sudanese origin. On the continent’s eastern coast, Arabic vocabulary was absorbed into the Bantu languages to form the Swahili language. On the other hand, in many cases conversion for sub-Saharan Africans was probably a way to protect themselves against being sold into slavery, a flourishing trade between Lake Chad and the Mediterranean. For their rulers, who were not active proselytizers, conversion remained somewhat formal, a gesture perhaps aimed at gaining political support from the Arabs and facilitating commercial relationships. The strongest resistance to Islam seems to have emanated from the Mossi and the Bamana, with the development of the Ségou kingdom. Eventually, sub-Saharan Africans developed their own brand of Islam, often referred to as “African Islam,” with specific brotherhoods and practices.
