Mughira b. Shu'ba wrote to Mu'awiya:When the Messenger of Allah (ﷺ) finished the prayer and pronounced salutation he uttered (this supplication):" There is no god but Allah. He is alone, Who has no partner. To Him belongs the sovereignty and to Him praise is due and He is Potent over every. thing. O Allah! no one can withhold what Thou givest, or give what Thou withholdest, and the riches cannot avail a wealthy person with Thee
