Volume 9, Book 93, Number 502:
Narrated Abu Huraira:
The Prophet said, “Allah says: ‘I am just as My slave thinks I am, (i.e. I am able to do for him what
he thinks I can do for him) and I am with him if He remembers Me. If he remembers Me in himself, I
too, remember him in Myself; and if he remembers Me in a group of people, I remember him in a
group that is better than they; and if he comes one span nearer to Me, I go one cubit nearer to him;
and if he comes one cubit nearer to Me, I go a distance of two outstretched arms nearer to him; and
if he comes to Me walking, I go to him running.’ “
