Those who believe, and work righteousness,- their Lord will guide them because of their faith: beneath them will flow rivers in gardens of bliss. (This will be) their cry therein: "Glory to Thee, O Allah." And "Peace" will be their greeting therein! and the close of their cry will be: "Praise be to Allah, the Cherisher and Sustainer of the worlds!"
It is related that the Prophet said, "None of you should come to me with anything about any of my Companions for I do not want to go out to you except with a clear heart.” (Abu Dawud and at-Tirmidhi from Ibn Mas'ud)
