Whoever Allah wills to guide, He opens their heart to Islam.1 But whoever He wills to leave astray, He makes their chest tight and constricted as if they were climbing up into the sky. This is how Allah dooms those who disbelieve.
— Dr. Mustafa Khattab, the Clear Quran
So whoever Allah wants to guide - He expands his breast to [contain] Islām; and whoever He wants to send astray1 - 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.
