Muslim armies conquered the Sasanian empire.

Muslim armies conquered the Sasanian empire. This is the correct answer. During the 650s and 660s, Muslim armies, led by the Rashidun Caliphs, launched military campaigns and successfully conquered the Sasanian Empire, which encompassed much of Southwest Asia. This military expansion contributed to the spread of Islam in the region, as the conquered territories were gradually converted to Islam by the Muslim rulers and their followers.
