Allah the Almighty says: “I am as My servant thinks I am. I am with him when he makes mention of Me. If he makes mention of Me to himself, I make mention of him to Myself; and if he makes mention of Me in an assembly, I make mention of him in an assembly better than it. And if he draws near to Me an arm’s length, I draw near to him a fathom’s length. And if he comes to Me walking, I go to him at speed.”

Buhkari, Muslim, at-Tirmidhi and Ibn-Majah. Hadith Qudsi narrated by Abu Hurairah.
