Suhaib reported the Apostle (ﷺ) saying: When those deserving of Paradise would enter Paradise, the Blessed and the Exalted would ask: Do you wish Me to give you anything more? They would say: Hast Thou not brightened our faces? Hast Thou not made us enter Paradise and saved us from Fire? He (the narrator) said: He (God) would lift the veil, and of things given to them nothing would he dearer to them than the sight of their Lord, the Mighty and the Glorious.
