Shu'ayb ibn Ahmad

Shu'ayb ibn Ahmad (شعيب بن أحمد) was the eighth Emir of Crete, reigning from c. 940–943.

The surviving records on the internal history and rulers of the Emirate of Crete are very fragmentary. He is tentatively identified as a son of the seventh emir, Ahmad ibn Umar, and as the great-great-grandson of the conqueror of Crete and founder of the emirate, Abu Hafs Umar. He is believed to have reigned from c. 940 to c. 943, succeeding his father, and being succeeded by his brother, Ali.
