[Saheeh Al-Bukhaari–Softening of the hearts—with short comments from Imaam Bin Baaz] Paradise is nearer to any of you than….
Narrated Abdullaah (radiyallaahu-anhu): ”The Prophet (sallal-laahu-alayhi-wasallam) said: Paradise is nearer to any of you than the Shiraak (leather strap) of his shoe, and so is the (Hell) fire.” 
Imaam Abdul-Azeez Bin Baaz (rahimahullaah) said: This (i.e. the above speech of the Prophet) is from Jawaami Al-kalim (i.e. a short expression with a vast meaning). There is nothing between him (i.e. a person) and paradise except dying (in a state) of Imaan and (that can be within) a few moments. And there is nothing between him and the hell fire except dying (in a state) of disbelief and (that can be within) a few moments.
