It was narrated that ‘Abdullah said: “When we sat during the prayer with the Messenger of Allah صلی اللہ علیہ وآلہ وسلم we used to say: ‘Peace (Salam) be upon Allah, peace be upon so-and-so and so-and-so.’ The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘Do not say: Peace (Salam) be upon Allah, for Allah isAs-Salam (the Source of Peace; the One free from all faults). Rather say: At tahiyyatu lillahi wa was atyibatu, as-salamu ‘alayka ayyuhan Nabiyyu wa ratzmat-Allahi wa barakatuhu. As-salamu ‘alayna wa ‘ala ‘ibadillahis-salihin (All compliments, prayers and pure rords are due to Allah. Peace be tipon you, Prophet, and the mercy of Allah and His blessings. Peace be upon us and upon the righteous laves of Allah). If you say that, it will be for every righteous slave in the heavens and on Earth, “Ashhadu an I ilaha ill-Allah wa ashhadu anna Mu ‘abduhu wa rast luhu (I bear witness that none has the right to be worshipped except Allah and I bear witness that Muhammad is His slave and Messenger). Then let him choose any supplication that he likes to say after that.” (Sahih)
