The word(s) "expand" appears 5 time(s) in 5 verse(s) in Quran in Saheeh International translation.

(1) So whoever Allah wants to guide - He expands his breast to [contain] Islam; and whoever He wants to misguide - He makes his breast tight and constricted as though he were climbing into the sky. Thus does Allah place defilement upon those who do not believe.

(2) [Moses] said, "My Lord, expand for me my breast [with assurance]

(3) So is one whose breast Allah has expanded to [accept] Islam and he is upon a light from his Lord [like one whose heart rejects it]? Then woe to those whose hearts are hardened against the remembrance of Allah. Those are in manifest error.

(4) And the heaven We constructed with strength, and indeed, We are [its] expander.

(5) Did We not expand for you, [O Muhammad], your breast?
