Narrated by Abu Hurayrah (Radi Allah Ta'lah Anhu).
”Allah Almighty said “I am as My servant expects Me to be. I am with him if he remembers Me. If he remembers Me to himself, I would remember him to Myself. And if he remembers Me in a gathering, I would remember him in a gathering, which is even better. And if My servant draws near to Me by a hand’s span, I would draw near to him by an arm’s length and if he draws near to Me by an arm’s length, I would draw near to him by a fathom’s length. And if My servant comes to me walking, I would go to him speeding.” (Al-Bukhari)
