Salaam and Greetings of Peace:
God has declared: “I am close to the thought that My servant has of Me, and I am with him whenever he recollects Me. If he remembers Me in himself, I remember him in Myself, and if he remembers Me in a gathering, I remember him better than those in the gathering do, and if he approaches Me by as much as one hand’s length, I approach him by a cubit, and if he approaches Me by a cubit, I approach him by two hands’ length. If he takes a step towards Me, I run towards him.”
– A hadith of the Prophet (pbuh)
Note: A cubit is an ancient linear unit, 17 to 21 inches (43 to 53 cm).
