Answer
Seeking Support in God was the regnal name of al-Mu'tadid, the Abbasid caliph who ruled from 892 to 902 CE. The regnal name, or laqab, was a title adopted by caliphs upon their accession to the throne and often reflected their personal qualities or aspirations. In the case of al-Mu'tadid, the name "Seeking Support in God" conveyed his reliance on divine assistance in governing the vast Abbasid empire.
