‘A’isha said that when God’s Messenger uttered the salutation he sat no longer than it took to say, “O God, Thou art Peace, and peace comes from Thee. Blessed art Thou, O Possessor of glory and honour.”
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.”
