Explanation:

The gold-salt trade on the trans-Saharan route flourished during the Middle Ages, particularly from the 8th to the 17th century. This trade connected various different regions, and it traded goods such as gold, salt and slaves. However, Islam predates this peak of trade by several decades. Islam had already spread in Africa by the mid-seventh century. Therefore, we can conclude that first, Arabs came to North Africa, and Islam spread throughout Africa. After North Africa came under Muslim rule, the trans-Saharan route flourished.
