Surah Al-Fajr, Ayah 26

On the Day of Judgement Everyone will be recompensed according to what He did of Good or Evil

Allah informs of what will happen on the Day of Judgement of the great horrors. He says,

كَلاَّ

(Nay!) meaning, truly.

إِذَا دُكَّتِ الاٌّرْضُ دَكّاً دَكّاً

(When the earth is flatened, Dakkan Dakka.) meaning, the earth and the mountains will be flattened, leveled and made even, and the creatures will rise from their graves for their Lord.

وَجَآءَ رَبُّكَ

(And your Lord comes) meaning, for the session of Judgement between His creatures. This is after they requested the best of the Sons of Adam -- Muhammad ﷺ-- to intercede with Allah. This will occur only after they have requested the other great Messengers, one after another. Yet, all of them will say, "I cannot do that for you." This will continue until the beseeching of the men reaches Muhammad ﷺ, and he will say, "I will do it, I will do it." So he will go and seek to intercede with Allah as the session of Judgement will have come, and Allah will allow him to intercede for that (the Judgement). This will be the first of the intercessions, and it is the praiseworthy station that has already been discussed in Surat Subhan (Al-Isra'). So Allah will come for the session of Judgement as He wills, and the angels will also come, lined up in rows upon rows before Him. Then Allah says,

يَوْمَئِذٍ يَتَذَكَّرُ الْإِنسَانُ وَأَنَّىٰ لَهُ الذِّكْرَىٰ (it will be the day when man will realise the truth, but from where will he take advantage of such realisation? - 89-23). The word tadhakkur in this context means 'to realise'. The unbelievers will realise the errors of their ways in the Hereafter, but it will be too late, because it is this present world where 'Imn and good deeds benefit the people. The Hereafter is the place only for reckoning and retribution. Man will express his remorse thus:

يَقُولُ يَا لَيْتَنِي قَدَّمْتُ لِحَيَاتِي (He will say, "0 Would that I had sent ahead [ some good deeds ] for [ this ] my life!"....89:24). When he faces the torment of disbelief and idolatry on that day of devastation, man will lament that he should have carried out good deeds and refrained from sin in this world to be saved from punishment in the Hereafter. But it will be of no avail. Allah says: 'So, that day, no one can punish like He will punish, nor can anyone shackle like He will shackle....89:26] Having described the torment of the unbelievers, the conclusion of the Surah gives cheerful news to the believers that they will be admitted into Paradise. Thus it says:

Man passes through two sets of circumstances in the world—sometimes finding or receiving things and sometimes losing them. Both eventualities, meant to gauge human reactions to different conditions, are for the purpose of putting man to the test. If the individual starts to boast when he receives something and acts negatively when things are taken away from him, he has failed the test.
