Verses 7 and 8 لَقَدْ حَقَّ الْقَوْلُ عَلَىٰ أَكْثَرِ‌هِمْ فَهُمْ لَا يُؤْمِنُونَ إِنَّا جَعَلْنَا فِي أَعْنَاقِهِمْ أَغْلَالًا (The word has indeed come true about most of them, so they will not believe. Surely We have placed iron collars on their necks, so they are reaching up to their chins, and their heads are forced to remain upraised.) mean that Allah Ta’ ala has already placed before human beings two alternate ways of life - the way of kufr (disbelief) and 'Iman (faith) and the way of Jannah (Paradise) and Jahannam (the Hell) - and to give direction and substance to this call of faith, He also sent prophets and Books. In fact, He went further ahead by giving human beings the choice to first identify what is good or bad for one and then take to either of the two ways. Now if there is that unfortunate person who does neither think, nor ponders over proofs spread throughout nature, nor listens to the call of the prophets, nor deliberates in the Book of Allah, then, once this person has made a choice and has taken to a way thus chosen, Allah Ta’ ala assembles for him everything he needs to achieve that end. One who embraces the wont of disbelief, for him the supply of things and circumstances that would increase his disbelief never run short. This is what has been expressed as: لَقَدْ حَقَّ الْقَوْلُ عَلَىٰ أَكْثَرِ‌هِمْ فَهُمْ لَا يُؤْمِنُونَ (7) which means that against most of these people, because of their choice of the evil, the decisive verdict of Allah - that they are not going to believe - already stands pronounced.

Given next is a similitude of their condition by saying that they look like people whose necks have been shackled in a manner that causes their faces and eyes stay upraised rendering them totally unable to see their way on the ground. If so, it is obvious that one cannot remain safe against the likelihood of falling down into some ditch or abyss.

Then comes another similitude. It was said that it is like a wall having been placed as a barrier all around someone. Thus surrounded, this person becomes unaware of what is going on outside. Similarly, these infidels are surrounded by their ignorance and, on top of it, by their hostility and doggedness. Under these conditions, it is as if the truth present elsewhere simply does not reach them.

Imam Razi (رح) has said that there are two kinds of barriers against perception. One barrier is of the kind that prevents one from seeing even himself. The second barrier is the inability to see one's surrounding. For the disbelievers, both kinds of barriers against seeing the truth were present. Therefore, the first example is that of the first barrier, that is, one who cannot bend his neck to lower his eyes cannot see even his own self or the state in which he exists. Then the second example is that of the second barrier that stops one from seeing his surroundings. (Ruh-ul- Ma’ ani)

The majority of commentators have declared the present verse to be a similitude of their disbelief and hostility only. And some commentators, on the basis of some narrations, have taken it to be the description of an event, that is, Abu Jahl and some others, bent on killing or hurting the Holy Prophet ﷺ ، lunged towards him but Allah Ta’ ala cast curtain over their eyes. Thus, rendered helpless, they went back. Many similar events have been reported in books of Tafsir, such as, Ibn Kathir, Ruh-ul-Ma’ ani, al-Qurtubi, Mazhari and others. But, most of these are weak narrations. The Tafsir of the verse cannot be based on such sources.
