Narrated ‘Abdullah : When we prayed with the prophet (S) we used to say , “Peace be on Allah from His slaves and peace be on so and so .” The prophet (S) said , “Don’t say As-Salam be on Allah , for He Himself is As-Salam ,but say , ‘At-tahiyatu lil -lahi was -salawatu wat-taiyibatu . As-salamu ‘Alaika aiyuhan -Nabiyu warahmatu – l – lahi wa barakatuhu . As salamu ‘alaina wa ‘ala ibadillahis -salihin . ( If you say this than it will be for all the slaves in heaven or between heaven and earth ) . Ashhadu an la-ilaha illallahu wa ashhadu anna Muhammadan ‘Abduhu wa Rasuluhu .’ Then select the invocation you like best and recite it .”
