On the authority of Abu Harayrah (may Allah be pleased with him), who said that the Prophet (Allah bless him and give him peace) said: Allah the Almighty said: 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 assemble 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. It was related by al-Buhkari (also by Muslim, at-Tirmidhi and Ibn-Majah). Imam Nawawi's 40 Hadith Qudsi
