Question:

Who introduced Islam into west Africa?

Answer:

The presence of Islam in Africa can be traced to the 7th century CE, when in Rajab 8 BH, or May 614 CE, Muhammad advised a number of his early disciples, who were facing persecution by the polytheistic inhabitants of the Mecca, to seek refuge across the Red Sea in Axum.

This led to the introduction of Islam in West Africa.
