What shores did the ancient Arab navigators reach?

In the seventh-eighth centuries, Arab tribes captured the entire Arabian Peninsula and North Africa, after which they began to actively establish trade relations with various Asian countries, especially with India. They also mastered the way to some islands in the Indian Ocean. So, the Arabs opened the road to the central parts of the eastern coast of Africa, reached the shores of the island of Zanzibar, as well as the shores of modern Tanzania and Mozambique. In addition, they opened the way to the Maldives, Mauritius, Seychelles, Indonesia and Malaysia.
