2:88
وَقَالُوا۟ قُلُوبُنَا غُلْفٌۢ ۚ بَل لَّعَنَهُمُ ٱللَّهُ بِكُفْرِهِمْ فَقَلِيلًا مَّا يُؤْمِنُونَ
waqālū qulūbunā ghul'fun bal laʿanahumu l-lahu bikuf'rihim faqalīlan mā yu'minūna
And they said, "Our hearts are wrapped." But, [in fact], Allāh has cursed them for their disbelief, so little is it that they believe.
— Saheeh International
They say, ‘Our hearts are impenetrably wrapped [against whatever you say],’ but God has rejected them for their disbelief: they have little faith.
— M. A. S. Abdel Haleem
And they say, "Our hearts are wrapped (i.e. do not hear or understand Allâh’s Word)." Nay, Allâh has cursed them for their disbelief, so little is that which they believe.
