islam was introduced into west africa by\nmissionaries\nprophets\ntraders\nnomads

Brief Explanations:

Islam spread to West Africa mainly through trade. Traders from North Africa and the Sahara region carried Islamic beliefs and practices as they engaged in commercial activities. Missionaries played a role later but were not the initial main introducers.

Nomads also had some influence but trade - related interactions (traders) were more significant for the initial spread.
