فَمَن يُرِدِ ٱللَّهُ أَن يَهْدِيَهُۥ يَشْرَحْ صَدْرَهُۥ لِلْإِسْلَـٰمِ ۖ وَمَن يُرِدْ أَن يُضِلَّهُۥ يَجْعَلْ صَدْرَهُۥ ضَيِّقًا حَرَجًا كَأَنَّمَا يَصَّعَّدُ فِى ٱلسَّمَآءِ ۚ كَذَٰلِكَ يَجْعَلُ ٱللَّهُ ٱلرِّجْسَ عَلَى ٱلَّذِينَ لَا يُؤْمِنُونَ

 - Mohammad Asad
Whomever Allah wills to guide, He opens his chest to Islam and whomever He intends to confound, He makes his chest narrow and squeezes so tight that, at the very idea of Islam, he feel as if his soul is going to climb up towards the sky. That is how Allah places a blight on those who do not believe,
 - Muhammad Farooq-i-Azam Malik
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.
 - Mustafa Khattab
And whomsoever it is Allah's will to guide, He expandeth his bosom unto the Surrender, and whomsoever it is His will to send astray, He maketh his bosom close and narrow as if he were engaged in sheer ascent. Thus Allah layeth ignominy upon those who believe not.
 - Marmaduke Pickthall
Those whom Allah (in His Plan) willeth to guide He openeth their breast to Islam; those whom He willeth to leave straying He maketh their breast close and constricted as if they had to climb up to the skies: thus doth Allah (heap) the penalty on those who refuse to believe. 947
