إِنَّا جَعَلْنَا فِي أَعْنَاقِهِمْ أَغْلَالًا فَهِيَ إِلَى الْأَذْقَانِ فَهُم مُّقْمَحُونَ (8)
(36:8) We have put fetters around their necks which reach up to their chins so that they are standing with their heads upright, *6
*6) "Fetters" in this verse implies their own stubbornness which was preventing them from accepting the truth. "Which reach to their chins" and "their standing with heads upright" implies the stiffness of the neck which is caused by pride and haughtiness. Allah means to impress this: "We have made their obstinacy and stubbornness the fetters of their neck, and their pride and haughtiness has made them so stiff-necked that they will not pay heed to any reality, however clear and evident it may be."
