﴿ وَقَالُوا۟ قُلُوبُنَا غُلْفٌۢ ۚ بَل لَّعَنَهُمُ ٱللَّهُ بِكُفْرِهِمْ فَقَلِيلًۭا مَّا يُؤْمِنُونَ ﴾

“But they say, "Our hearts are already full of knowledge." Nay, but God has rejected them because of their refusal to acknowledge the truth: for, few are the things in which they believe.”

And they say: �Our hearts are encased.� Nay but God has cursed them for their unbelief; and little will they believe. If there had been anything in them free of pretension it would have become easy to find meanings [from God's signs and scripture]. But when [they must] recognize the truth the fangs of pretenders are bared... It is said: When tears flow down cheeks The one who is crying is distinguished from the one who is only pretending.
