Dar es Salaam is the former capital of Tanzania and the largest city in the country in terms of population, with about 3 million people living in it. This city is located on the eastern coast of the country overlooking the Indian Ocean. Dar El-Sam enjoys a high degree of autonomy, as it is managed in a semi-autonomous manner. Many Arab merchants settled in this city and mixed with its inhabitants, and they learned their Bantu language, while they taught them the Arabic language, and with time the two languages merged to give rise to the Swahili language. The Arabs have migrated to Dar es Salaam since the Umayyad era, and they settled and frequented it to trade goods between the Arabian Peninsula and East Africa. Therefore, you will see that the Islamic religion is spread among the inhabitants of this city.
