And those who disbelieve say: "We believe not in this Qur'an nor in that which was before it." But if you could see when the wrongdoers are made to stand before their Lord, how they will cast the (blaming) word one to another! Those who were deemed weak will say to those who were arrogant: "Had it not been for you, we should certainly have been believers! (31)And those who were arrogant will say to those who were deemed weak: "Did we keep you back from guidance after it had come to you? Nay, but you were criminals. (32)Those who were deemed weak will say to those who were arrogant: "Nay, but it was your plotting by night and day, when you ordered us to disbelieve in Allah and set up rivals to Him!" And each of them (parties) will conceal their own regrets, when they behold the torment. And We shall put iron collars round the necks of those who disbelieved. Are they requited aught except what they used to do (33)

How the Disbelievers have agreed in this World to deny the Truth, and how They will dispute with One Another on the Day of Ressurection

Allah tells us about the excessive wrongdoing and stubbornness of the disbelievers, and their insistence on not believing in the Holy Qur'an and what it tells them about the Resurrection. Allah says:

وَقَالَ الَّذِينَ كَفَرُوا لَنْ نُؤْمِنَ بِهَٰذَا الْقُرْآنِ وَلَا بِالَّذِي بَيْنَ يَدَيْهِ ۗ 

(And those who disbelieve say: "We believe not in this Qur'an nor in that which was before it.") Allah threatens them and warns them of the humiliating position they will be in before Him, arguing and disputing with one another:

يَرْجِعُ بَعْضُهُمْ إِلَىٰ بَعْضٍ الْقَوْلَ يَقُولُ الَّذِينَ اسْتُضْعِفُوا

(how they will cast the (blaming) word one to another! Those who were deemed weak) this refers to the followers –

 لِلَّذِينَ اسْتَكْبَرُوا 

(to those who were arrogant) – this refers to the leaders and masters –

لَوْلَا أَنْتُمْ لَكُنَّا مُؤْمِنِينَ 

(Had it not been for you, we should certainly have been believers!) meaning, 'if you had not stopped us, we would have followed the Messengers and believed in what they brought.' Their leaders and masters, those who were arrogant, will say to them:

 أَنَحْنُ صَدَدْنَاكُمْ عَنِ الْهُدَىٰ بَعْدَ إِذْ جَاءَكُمْ

(Did we keep you back from guidance after it had come to you?) meaning, 'we did nothing more to you than to call you, and you followed us without any evidence or proof, and you went against the evidence and proof which the Messengers brought because of your own desires; it was your own choice.' They will say:

بَلْ كُنْتُمْ مُجْرِمِينَ - وَقَالَ الَّذِينَ اسْتُضْعِفُوا لِلَّذِينَ اسْتَكْبَرُوا بَلْ مَكْرُ اللَّيْلِ وَالنَّهَارِ

("...Nay, but you were criminals." Those who were deemed weak will say to those who were arrogant: "Nay, but it was your plotting by night and day...") meaning, 'you used to plot against us night and day, tempting us with promises and false hopes, and telling us that we were truly guided and that we were following something, but all of that was falsehood and manifest lies.' Qatadah and Ibn Zayd said:

بَلْ مَكْرُ اللَّيْلِ وَالنَّهَارِ

(Nay, but it was your plotting by night and day,) means, "You plotted by night and day." Malik narrated something similar from Zayd bin Aslam.

 إِذْ تَأْمُرُونَنَا أَنْ نَكْفُرَ بِاللَّهِ وَنَجْعَلَ لَهُ أَنْدَادًا

(when you ordered us to disbelieve in Allah and set up rivals to Him!) means, 'to set up gods as equal to Him, and you created doubts and confusion in our minds, and you fabricated far-fetched ideas with which to lead us astray.'

وَأَسَرُّوا النَّدَامَةَ لَمَّا رَأَوُا الْعَذَابَ 

(And each of them (parties) will conceal their own regrets, when they behold the torment.) means, both the leaders and the followers will feel regret for what they did previously.

وَجَعَلْنَا الْأَغْلَالَ فِي أَعْنَاقِ الَّذِينَ كَفَرُوا

(And We shall put iron collars round the necks of those who disbelieved.) This is a chain which will tie their hands to their necks.

هَلْ يُجْزَوْنَ إِلَّا مَا كَانُوا يَعْمَلُونَ

(Are they requited aught except what they used to do?) means, they will be punished according to their deeds: the leaders will be punished according to what they did, and the followers will be punished according to what they did.

قَالَ لِكُلٍّ ضِعْفٌ وَلَٰكِنْ لَا تَعْلَمُونَ

(He will say: "For each one there is double (torment), but you know not.")(7:38). Ibn Abi Hatim recorded that Abu Hurayrah, may Allah be pleased with him, said, "The Messenger of Allah ﷺ said:

إِنَّ جَهَنَّمَ لَمَّا سِيقَ إِلَيْهَا أَهْلُهَا تَلَقَّاهُمْ لَهَبُهَا، ثُمَّ لَفَحَتْهُمْ لَفْحَةً فَلَمْ يَبْقَ لَحْمٌ إِلَّا سَقَطَ عَلَى الْعُرْقُوبِ

(When the people of Hell are driven towards it, it will meet them with its flames, then the Fire will burn their faces and the flesh will all fall to their hamstrings.)"
