Book Number: 002 / Hadith Number: 1500
Narated By Al Mughairah b. Shu'bah : Mu'awiyah wrote to al-Mughairah b. Shu'bah: What would the Apostle of Allah (pbuh) recite when he gave the salutations in prayer? Al-Mughaira dictated and wrote to Mu'awiyah: The Apostle of Allah (pbuh) used to say (at the end of prayer after salutations) : "There is no god but Allah, Alone, Who has no partner; to Him belongs the dominion, to Him praise is due, and He is Omnipotent. O Allah no one can withhold what Thou givest, or give what Thou withholdest, and riches cannot avail a wealthy person with Thee.
