Arab merchants played a large role in this growing spread in this trade growth of trade was also linked to the growth of the new religion called Islam. the father of Islam was named Muhammad the bible name was Qumran. Muhammad won many followers among Arabist. After his death in 632, Islam spread rapidly. Muslims merchants traded across a vast area. they sailed to parts around the Indian ocean. Muslims sailors had experts knowledge of wind and weather conditions of the Indian ocean.
