Some of the earliest accounts concerning the island of Comoros are derived from the works of Al-Masudi, which mention the importance of the Comoro Islands, like other coastal areas in the region, along early Islamic trade routes and how the islands are frequently visited by Muslims including Persian and Arab merchants and sailors from Basra in search of coral, ylang-ylang, ivory, beads, spices, gold.

They also bring Islam to the people of the Zanj, including Comoros.

Al-Masudi in the year 933 mentions Muslim sailors who call the Comoros islands: "the Perfume Islands" and sing of waves that break rhythmically along broad, pearl-sand beaches, the light breezes scented with vanilla and ylang-ylang, a component in many perfumes.
