55وَلَا يَزَالُ ٱلَّذِينَ كَفَرُوا۟ فِى مِرْيَةٍ مِّنْهُ حَتَّىٰ تَأْتِيَهُمُ ٱلسَّاعَةُ بَغْتَةً أَوْ يَأْتِيَهُمْ عَذَابُ يَوْمٍ عَقِيمٍ
56ٱلْمُلْكُ يَوْمَئِذٍ لِّلَّهِ يَحْكُمُ بَيْنَهُمْ ۚ فَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ فِى جَنَّـٰتِ ٱلنَّعِيمِ
57وَٱلَّذِينَ كَفَرُوا۟ وَكَذَّبُوا۟ بِـَٔايَـٰتِنَا فَأُو۟لَـٰٓئِكَ لَهُمْ عَذَابٌ مُّهِينٌ
58وَٱلَّذِينَ هَاجَرُوا۟ فِى سَبِيلِ ٱللَّهِ ثُمَّ قُتِلُوٓا۟ أَوْ مَاتُوا۟ لَيَرْزُقَنَّهُمُ ٱللَّهُ رِزْقًا حَسَنًا ۚ وَإِنَّ ٱللَّهَ لَهُوَ خَيْرُ ٱلرَّٰزِقِينَ
59لَيُدْخِلَنَّهُم مُّدْخَلًا يَرْضَوْنَهُۥ ۗ وَإِنَّ ٱللَّهَ لَعَلِيمٌ حَلِيمٌ
60ذَٰلِكَ وَمَنْ عَاقَبَ بِمِثْلِ مَا عُوقِبَ بِهِۦ ثُمَّ بُغِىَ عَلَيْهِ لَيَنصُرَنَّهُ ٱللَّهُ ۗ إِنَّ ٱللَّهَ لَعَفُوٌّ غَفُورٌ
[55-60] Yet the disbelievers will always remain in doubt about it until the Hour of Resurrection overtakes them suddenly or the scourge of a "barren" day102 descends upon them. On that Day Allah will reign supreme, and He will judge between them; then those who will have believed and done righteous works, will go to the Gardens of Bliss, but those who will have disbelieved and treated Our Revelations as false, shall receive an ignominious punishment. As for those, who left their homes for the sake of Allah and then were killed or died, Allah will make for them a generous provision) and Allah is the best of Providers. He will admit them to a place with which they will be well pleased; indeed Allah is All-Knowing and Clement.103 This is about them. As regards the one, who takes vengeance equal to the wrong that had been done to him, and has again been oppressed, Allah will surely help him.104 Allah is Forgiving and Forbearing.105
102The epithet "barren" has been applied to the "day" in its metaphorical and not literal sense. :A "day" is barren if all the plans, hopes and devices remain unproductive in it, or it does not bring forth its night. For instance, the days on which the people of Prophet Noah, the tribes of `Ad and Thamud, the people of Lot and of Midian met with their destruction by scourge from Allah, were barren days in this sense, because those days did not bring forth any "tomorrow" for them, and no device of theirs could avert their doom.
103As Allah is All-Knowing, He knows well those who left their homes for His sake and what reward they deserve. He is Clement, and forgives minor errors and weaknesses of the people; therefore these things will not hinder Him from rewarding the Believers for their services and sacrifices.
104The preceding verses referred to those persecuted people who could not retaliate and here 'the reference is to those victims of persecution who could fight back.
From this verse, Imam Shafi`i has concluded that "retaliation" will be effected in the way as life was taken in the original act. If a person is killed by immersion in water, the killer also should be put to death by immersion in water; or if a person is .burnt to death, the killer also will be burnt to death. The Hanafites dispute this. According to them, retaliation against a murderer will be incurred in one and the same established way no matter how life was taken by the culprit in the original act.
105This verse (60) may imply two things:
(1) Allah forgives that "killing" which is done in self-defense, though killing of people is not a good thing in itself. (2) As Allah, Whose slaves the Believers are, is Forgiving and Forbearing, they should also forgive and forbear as far as possible. Though they have the right of retaliation, they should not resort to carnage and massacre.
