Sahih Muslim 593 e
Kitabu cha Misikiti na Mahali pa Kuswali
It is recommended to recite statements of remembrance after the prayer, and how that is to be done
Warrad, the scribe of Mughira b. Shu'ba, reported: Mu'awiya wrote to Mughira: Write to me anything which you heard from the Messenger of Allah (ﷺ). So he (Mughira) wrote to him (Mu'awiya): I heard the Messenger of Allah (ﷺ) uttering (these words) at the completion of prayer:" There is no god but Allah. He is alone and there is no partner with Him. Sovereignty belongs to Him and to Him is praise due and He is Potent over everything. O Allah! no one can withhold what You givest, or give what You withholdest, and riches cannot avail a wealthy person with You."
