Allah, the Exalted, says:
"Verily, those who believe and do deeds of righteousness, their Rubb will guide them through their Faith; under them will flow rivers in the Gardens of Delight (Jannah). Their way of request therein will be Subhanaka Allahumma (Glory to You, O Allah!) and Salam (peace, safety from evil) will be their greetings therein (Jannah)! and the close of their request will be: Al-hamdu lillahi Rabbil-'Alamin [All the praises and thanks are to Allah, the Rubb of 'Alamin (mankind, jinn and all that exists)]." (10:9,10)
