Al Baqarah, 88 Ayah
2:88
وَقَالُواْ قُلُوبُنَا غُلۡفُۢۚ بَل لَّعَنَهُمُ ٱللَّهُ بِكُفۡرِهِمۡ فَقَلِيلٗا مَّا يُؤۡمِنُونَ ٨٨
Wa Qālū Qulūbunā Ghulfun ۚ Bal La`anahumu Al-Lahu Bikufrihim Faqalīlāan Mā Yu'uminūna
And they said, "Our hearts are wrapped." But, [in fact], Allah has cursed them for their disbelief, so little is it that they believe.
