Is it permissible to perform tasbih using the Beautiful Names of Allah, such as saying "Subhan Allah Al-Wahhab Ar-Razzaq" a hundred times, and does one receive reward for doing so?

Glorifying Allah Almighty with His Beautiful Names is a virtuous and permissible act, and its doer is rewarded for it, as Allah Almighty says: "Say, 'Call upon Allah or call upon Ar-Rahman. Whichever [name] you call upon - to Him belong the best names," and His saying: "And to Allah belong the best names, so invoke Him by them." It has been narrated in the Sunnah that the Prophet, peace and blessings be upon him, glorified Allah with names such as "Subhan al-Malik al-Quddus" (Glory be to the Sovereign, the Most Holy), and "Subhan Dhi al-Jabarut wal-Malakut wal-Kibriyaa' wal-Azamah" (Glory be to the Possessor of Omnipotence, Sovereignty, Grandeur, and Might), and "Subhan Rabbi al-Azeem" (Glory be to my Lord, the Most Great), and "Subhan Rabbi al-A'la" (Glory be to my Lord, the Most High). This indicates the permissibility of glorifying Allah with any of His names, and that adhering to the narrated formulas yields a more complete reward.
