Kur’an 6:125 — sura Al-An'am, 125. ajet

فَمَن يُرِدِ ٱللَّهُ أَن يَهۡدِيَهُۥ يَشۡرَحۡ صَدۡرَهُۥ لِلۡإِسۡلَٰمِۖ وَمَن يُرِدۡ أَن يُضِلَّهُۥ يَجۡعَلۡ صَدۡرَهُۥ ضَيِّقًا حَرَجٗا كَأَنَّمَا يَصَّعَّدُ فِي ٱلسَّمَآءِۚ كَذَٰلِكَ يَجۡعَلُ ٱللَّهُ ٱلرِّجۡسَ عَلَى ٱلَّذِينَ لَا يُؤۡمِنُونَ

Onome koga Allah želi uputiti – On srce njegovo prema islamu raspoloži, a onome koga želi u zabludi ostaviti – On srce njegovo stegne i umornim učini kao kad čini napor da na nebo uzleti. Eto, tako Allah one koji ne vjeruju bez podrške ostavi.

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
