and whomsoever allah wills to guide he opens his breast to islam and whomsoever he wills to send astray he makes his breast closed and constricted as if he is climbing up to the sky. thus allah puts the wrath on those who believe not.
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
