أَفَمَن شَرَحَ ٱللَّهُ صَدْرَهُۥ لِلْإِسْلَـٰمِ فَهُوَ عَلَىٰ نُورٍ مِّن رَّبِّهِۦ ۚ فَوَيْلٌ لِّلْقَـٰسِيَةِ قُلُوبُهُم مِّن ذِكْرِ ٱللَّهِ ۚ أُو۟لَـٰٓئِكَ فِى ضَلَـٰلٍ مُّبِينٍ 22
Translations
So is one whose breast Allāh has expanded to [accept] Islām and he is upon [i.e., guided by] a light from his Lord [like one whose heart rejects it]? Then woe to those whose hearts are hardened against the remembrance of Allāh. Those are in manifest error.
Transliteration
Afaman sharaḥa Allāhu ṣadrahu lil-Islāmi fahuwa ʿalā nūrin min rabbihi, fawaylun lil-qāsiyati qulūbuhum min dhikri Allāh, ūlāʾika fī ḍalālin mubīn
Tafsir (Explanation)
This ayah presents a stark contrast between two spiritual states: those whose hearts Allah has opened (expanded/softened) for Islam, who walk in light from their Lord, and those whose hearts have hardened and turned away from remembrance of Allah, who are in manifest error. Classical scholars like Ibn Kathir emphasize that 'sharaḥ al-ṣadr' (opening of the breast) is Allah's special grace that removes obstacles from accepting faith, while 'qaswat al-qulūb' (hardness of hearts) represents spiritual obstinacy and rejection of divine signs. Al-Qurtubi notes that the contrast illustrates how receptiveness to divine guidance leads to illumination, while resistance leads to darkness and misguidance.
Revelation Context
This ayah appears in the Meccan surah Az-Zumar, which addresses the fundamental theological contrast between believers and disbelievers during the early Meccan period when the Prophet faced significant resistance to the message. The surah's broader context deals with monotheism and the consequences of accepting or rejecting Allah's message, with this particular ayah exemplifying the spiritual transformation that comes with sincere acceptance of Islam.
Related Hadiths
The Prophet ﷺ said: 'Indeed, when the servant commits a sin, a black spot appears on his heart. If he repents and seeks forgiveness, his heart is polished clean. But if he continues [in sin], the blackness increases until it covers his entire heart.' (Jami' at-Tirmidhi 3334) - This relates to the hardening of hearts mentioned in the ayah.

Key Lesson
The opening of one's heart to Islam is ultimately a divine gift from Allah, not merely a human achievement; our responsibility is to remain receptive, humble, and engaged with divine remembrance to prevent our hearts from hardening. For believers today, this ayah serves as a reminder that consistent engagement with Quranic study, dhikr (remembrance), and reflection strengthens spiritual perception, while heedlessness and distraction risk spiritual deterioration.
