The State of Those Who are decreed to be among the Doomed
Allah says: `In the case of those who are decreed to be among the doomed, when it comes to the matter of being guided, We have made them like a person who has a chain around his neck and whose hands are tied together beneath his chin so that his head is lifted up.' As Allah says:
فَهُم مُّقْمَحُونَ
(so that their heads are raised up.) Mentioning the chains around the neck is sufficient and there is no need to mention the hands, although they are referred to by implication. Al-`Awfi said, narrating from Ibn `Abbas, may Allah be pleased with him, concerning the Ayah:
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.
The Quran itself is the proof of Muhammad being the Prophet of God. The Quran calls mankind towards the right path, i.e. the path of righteousness. None of its contents clash with reason and nature. Even fifteen hundred years after the Quran was first revealed, nothing has been detected in it which can be called as irrational or unnatural. This distinct characteristic of the Quran is the greatest proof of its being the book of God. ‘So that you may warn a people.’ Here, ‘people’ refers to the Children of Isma‘il. Every prophet is raised primarily to address his contemporaries. Accordingly, the first addressees of the Prophet Muhammad were his own tribesmen. But although the institution of prophethood ended with him, the Prophethood of Muhammad shall continue until Doomsday—the difference being that, with the Children of Isma‘il, he personally and directly fulfilled his mission, while in respect of all other nations after him, the task of giving the call and fulfilling the mission shall have to be performed by his followers.
