الانعام — Al-An'am Ayat 125
فَمَنْ يُّرِدِ اللّٰهُ اَنْ يَّهْدِيَهٗ يَشْرَحْ صَدْرَهٗ لِلْاِسْلَامِۚ وَمَنْ يُّرِدْ اَنْ يُّضِلَّهٗ يَجْعَلْ صَدْرَهٗ ضَيِّقًا حَرَجًا كَاَنَّمَا يَصَّعَّدُ فِى السَّمَاۤءِۗ كَذٰلِكَ يَجْعَلُ اللّٰهُ الرِّجْسَ عَلَى الَّذِيْنَ لَا يُؤْمِنُوْنَ
Fa may yuridillāhu ay yahdiyahū yasyraḥ ṣadrahū lil-islām(i), wa may yurid ay yuḍillahū yaj‘al ṣadrahū ḍayyiqan ḥarajan ka'annamā yaṣṣa‘‘adu fis-samā'(i), każālika yaj‘alullāhur-rijsa ‘alal-lażīna lā yu'minūn(a).
"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."
