Surah At-Taghaabun (64) — Ayah 9

(Ayah 9) ➊ {يَوْمَ يَجْمَعُكُمْ لِيَوْمِ الْجَمْعِ:} is the adverbial phrase of {’’ لَتُبْعَثُنَّ ثُمَّ لَتُنَبَّؤُنَّ ‘‘}; the Day of Resurrection is called {’’ يَوْمُ الْجَمْعِ ‘‘} because on that day all the former and latter generations will be gathered in one plain. (See Hud: 103; As-Saffat: 49, 50; Ash-Shura: 7; Al-Mursalat: 38) The meaning of {’’يَوْمُ الْجَمْعِ‘‘} can also be that on that day every bone and every particle of a human's body, which had been scattered, will be gathered together, as He said: «اَيَحْسَبُ الْاِنْسَانُ اَلَّنْ نَّجْمَعَ عِظَامَهٗ» [ القیامۃ : ۳ ] "Does man think that We will never assemble his bones?"
➋ {ذٰلِكَ يَوْمُ التَّغَابُنِ: ’’غَبَنَ‘‘ (ن) ’’فُلَانًا فِي الْبَيْعِ‘‘} To gain benefit for oneself by causing loss to another in a transaction. At-Tabari has narrated with an authentic chain from Ali bin Abi Talhah from Ibn Abbas (may Allah be pleased with them both) regarding {’’ ذٰلِكَ يَوْمُ التَّغَابُنِ ‘‘}, he said: [هُوَ اسْمٌ مِّنْ أَسْمَاءِ يَوْمِ الْقِيَامَةِ وَذٰلِكَ أَنَّ أَهْلَ الْجَنَّةِ يَغْبُنُوْنَ أَهْلَ النَّارِ ] "That is, Yawm at-Taghabun is one of the names of the Day of Resurrection, and this name is because on that day the people of Paradise will gain benefit by putting the people of Hell in loss." Ibn Kathir (may Allah have mercy on him) said that the details of this profit and loss have been explained by Allah Himself further on, as to what the believers and doers of righteous deeds will receive and what will be the share of the disbelievers and deniers.
➌ {وَ مَنْ يُّؤْمِنْۢ بِاللّٰهِ وَ يَعْمَلْ صَالِحًا … :} This is the statement of the share of the winners among the winners and losers of that day.

9. 1. The Day of Judgment is called Yawm al-Jam‘ because on that day, all the first and the last will be gathered together in the same plain. Everyone will hear the voice of the angel, and each person's sight will reach to the end, because nothing will be obstructing in between.

9. 2. That is, one group will be victorious and one will be defeated; the people of truth over the people of the esoteric, the believers over the disbelievers, and the obedient over the disobedient will be victorious. The greatest victory for the believers will be that they will enter Paradise, and the greatest loss will be for the people of Hell, who will enter Hell.

On the Day He will gather you all together—the Day of Gathering, that is the Day of mutual loss and gain [17]. And whoever believes in Allah and does righteous deeds, He will remove his misdeeds from him and admit him into Gardens beneath which rivers flow, to abide therein forever. That is the supreme success.

Literal Explanation and Meaning of ﴿تغابن﴾:

﴿تغابن﴾ is a well-known word meaning to secretly usurp someone else's right, and ﴿غبن﴾ means to secretly try to deprive each other of rights, whether those rights pertain to wealth and property or to other rights. However, the ﴿تغابن﴾ that takes place in the world and continues to happen all the time is not real; rather, its results are the opposite. For example, if Zaid usurps Bakr's right, then in this world, the apparent situation is that Zaid has benefited and Bakr has suffered a loss. But on the Day of Judgment, when Bakr's usurped right is returned to him from Zaid, then Bakr will be in profit and Zaid will be in loss. Thus, in the Hereafter, the results of profit and loss will be opposite to those in the world. In this sense, Zaid lost and Bakr won. This meaning is also supported by the hadith in which the Messenger of Allah ﷺ asked the Companions (may Allah be pleased with them): "Do you know who is bankrupt?" The Companions replied: "The bankrupt is the one who has no money." He ﷺ said: "Truly, the bankrupt is the one who will come on the Day of Judgment with many good deeds, but those who are owed rights will come before Allah's court and demand their rights, so his good deeds will be given to the rightful claimants until he has no good deeds left." [مسلم۔ کتاب البر والصلۃ والادب۔ باب تحریم الظلم]

Now, moving from individuality to collectivity. One group is that which has oppressed the Muslims and made their lives miserable. And they think that they alone are dominant and successful. These people have devoted all their abilities and capabilities, time, and wealth to the task of erasing Islam from the face of the earth. The other group is the one that is being crushed under the oppression of these tyrants, and apparently, it seems that these people are subdued and overpowered. Whereas the reality is the opposite. When, on the Day of Judgment, the results of all these people's deeds come to light, it will become clear who was at a loss and who was at a profit, who lost and who won.
