Musannaf Ibn Abi Shaybah

Hazrat Warad, who was the freed slave of Hazrat Mughirah bin Shu’bah, narrates: Hazrat Mu’awiyah wrote a letter to Hazrat Mughirah bin Shu’bah and asked: What words did the Messenger of Allah (peace and blessings be upon him) say after concluding the prayer with salam? Hazrat Warad says that Hazrat Mughirah dictated those words to me, and he says that then I wrote those words and sent them to Hazrat Mu’awiyah. Indeed, when the Messenger of Allah (peace and blessings be upon him) would conclude the prayer with salam, he would say: “There is no god except Allah, who is alone, He has no partner, His is the dominion and for Him are all praises, and He is powerful over everything. O Allah! There is none who can withhold what You give, and none who can give what You withhold, and the status of any person of high rank cannot benefit him against You.”
