1. In the original the word mutaffifin has been used, which is derived from tatfif, a word used for an inferior and base thing in Arabic. Terminologically, tatfif is used for giving short weight and short measure fraudulently, for the person who acts thus while measuring or weighing, does not defraud another by any substantial amount, but skimps small amounts from what is due to every customer cleverly, and the poor customer does not know of what and of how much he is being deprived by the seller.

 At several places in the Quran, giving of short measure and weight has been condemned and measuring fully and weighing rightly has been stressed. In Surah Al-Anaam, it has been enjoined: You should use a full measure and a just balance. We charge one only with that much responsibility that one can bear. (verse 152). In Surah Bani Israil, it has been said: Give full measure when you measure and weigh with even scales. (verse 35). In Surah Ar-Rehman, it has been stressed: Do not upset the balance: weigh with equity and do not give short weight. (verses 8-9). The people of the Prophet Shuaib (peace be upon him) were punished for the reason that the evil of giving short measure and weight had become widespread among them and in spite of his counsel and advice they did not refrain from it.

 A Great Day: the Day of Resurrection when all men and jinn will be called to account together in the divine court and decisions of vital importance will be made pertaining to rewards and punishments.

4. That is, these people are wrong in thinking that they will be let off without being called to account when they have committed such and such crimes in the world. .

5. The word sijjin in the original is derived from sijn (a prison) and the explanation of it that follows shows that it implies the general register in which the actions and deeds of the people worthy of punishment are being recorded.

6. Our verses: Those verses in which news of the Day of Recompense has been given.

7. That is, they have no good reason for regarding the meting out of rewards and punishments as unreal. What has made them say is this: Is it that their hearts have become rusty because of their sins; therefore, a thing which is thoroughly reasonable appears unreal and unreasonable to them. The explanation of this rust as given by the Prophet (peace be upon him) is as follows: When a servant commits a sin, it marks a black stain on his heart. If he offers repentance, the stain is washed off, but if he persists in wrongdoing, it spreads over the entire heart. (Musnad Ahmad, Tirmidhi, Nasai, Ibn Majah, Ibn Jarir, Hakim, Ibn Abi Hatim, Ibn Hibban and others).

8. That is, these people will remain deprived of the vision of Allah with which the righteous will be blessed. (For further explanation, see (E.N. 17 of Surah Al -Qiyamah).

9. That is, they are wrong in thinking that there is going to be no meting out of rewards and punishments.

10. One meaning of the words khtamu-hu-misk is that the vessels containing the wine will carry the seal of musk instead of clay or wax. Accordingly the verse means: This will be the choicest kind of wine, which will be superior to the wine flowing in the canals, and it will be served by the attendants of Paradise in vessels sealed with musk to the dwellers of Paradise. Another meaning can also be: When that wine will pass down the throat, its final effect will be of the flavor of musk. This state is contrary to the wines of the world which give out an offensive smell as soon as the bottle opens and one feels its horrid smell even while drinking and also when it passes down the throat.

11. Tasneem means height. Thus, Tasnim will be a fountain flowing down from a height.

12. That is, they returned home rejoicing, thinking that they had made fun of such and such a Muslim, had passed evil remarks against him and subjected him to ridicule among the people.

13. That is, they have lost their reason. They have deprived themselves of the gains and enjoyments of the world and have experienced dangers and undergone hardships only for the reason that Muhammad (peace be upon him) has deluded them with the Hereafter, Heaven and Hell. They are giving up whatever is present here on the false hope that the promise of some Paradise has been held out to them after death, and they are enduring the hardships in the present life only for the reason that they have been threatened with some Hell in the next world.

14. In this brief sentence the mockers and jesters have been given an instructive warning to the effect: Even if what the Muslims have believed in, is false, they are not harming you at all. They regard something as true, and are accordingly adopting a certain moral attitude for themselves, for their own good. Allah has not appointed you to be keepers over them so that you may be free to criticize and persecute those who are not harming you in any way.

15. There is a subtle satire in this sentence. In the world, the disbelievers used to persecute the believers, thinking it was an act of virtue. In the Hereafter, the believers will be enjoying life in Paradise, and watching the disbelievers being punished in Hell. They will say to themselves: What a reward they have earned for their acts of virtue.
