whomever god desires to guide he spreads open his heart to islam and whomever he desires to misguide he makes his heart narrow constricted as though he were climbing up the sky. god thus lays defilement upon those who do not believe.
فمن يرد الله أن يهديه يشرح صدره للإسلام ومن يرد أن يضله يجعل صدره ضيقا حرجا كأنما يصعد في السماء كذلك يجعل الله الرجس على الذين لا يؤمنون
