Abu ʿAmr Shuʿayb ibn ʿUmar ibn ʿIsā al-Balluti, also Saet (Greek: Σαήτ) or Saïpes (Σαΐπης) in the Byzantine sources, was the second Emir of Crete, ruling c. 855 – c. 880.
The surviving records on the internal history and rulers of the Emirate of Crete are very fragmentary.
Following the studies of George C. Miles with the aid of numismatic evidence, his reign is tentatively placed from c. 855 to c. 880, although a gold dinar struck in his name is dated as late as 894/5.
Shu'ayb is also commonly identified with the "Saet" or "Saïpes" of the Byzantine chroniclers, Theophanes Continuatus, John Skylitzes, and Genesios.
[3][4] These Byzantine victories apparently led to a temporary truce, and it appears that Shu'ayb was obliged to pay tribute to Byzantium for about a decade.
