Al-Mughira b. Shu'ba stated that the Prophet used to say after every prescribed prayer, “There is no god but God alone, who has no partner. To Him belongs the kingdom, to Him praise is due, and He is omnipotent. O God, no one can withhold what Thou givest, or give what Thou withholdest, and riches cannot avail a wealthy person with Thee.”
(Bukhari and Muslim.)
