(101:8) but he whose scales weigh lighter, *4

But as for one whose scales are light, meaning

*4) The word mawazin in the original can be plural of mauzun as well as, of mizan. In the first case, mawazin would imply the deeds which might have some weight in the sight of Allah and be, thus, worthy of appreciation; in the second case, mawazin would imply scales of a balance. In the first case, the meaning of the mawazin's being heavier or lighter is that the good deeds will be heavy or light as ,against the evil deeds, for in the sight of Allah only good deeds have any weight and worth. In the second case. the meaning of the mawazin's being heavy is that the scale of the good deeds will be heavier than the scale of evil deeds, in Allah Almighty's Balance of Justice, and their being light means that the scale of good deeds will be lighter than the scale of evil deeds. Besides, in Arabic idiom the word mizan is also used for weight ( wazan); accordingly, the weight's being heavy of light implies the good deeds being heavy or light. In any case, whether mawazin is taken in the meaning of mauzun or of mizan, or of wazan, the intention remains the same, which is that the basis of judgement in the Divine Court will be whether the provision of the deeds that a matt has brought is weighty or weightless, or whether his good deeds are heavier than his evil deeds or lighter. This theme has occurred at several places in the Qur'an which explains the meaning fully well. In Surah Al-A'raf it has been said: "On that Day the weight will be identical with the Truth: accordingly, those whose scales, will be heavy will alone come out successful; and those whose scales are light will be the ones who will have incurred loss upon themselves." (w. 8-9). In Surah Al-Kahf, it was said: 'O Prophet, say to them: Should we tell you who are the most un-successful people and miserable failures in regard to their deeds? They are those whose all endeavours in the worldly life had gone astray from the Right Way, but they were under the delusion that everything they were doing, was rightly directed: these are the people who rejected the Revelations of their Lord and did not believe that they would ever go before Him. Therefore, all their deeds were Lost, for We will assign no weight to them on the Day of Resurrection." (vv. 103-105). In Surah Al-Anbiya': "On the Day of Resurrection, We will set up just and accurate balances so that no one will be wronged in the least in any way; even if it be an act equal in weight to a grain of mustard seed, We will bring it forth (to be weighed) and We suffice for reckoning". (v.47). These verses show that kufr and denial of the truth is in itself such a stupendous evil that it will certainly lower the scale of evils, and there will be no good act of the disbelievers, which may have any weight in the scale of good deeds so that its scale of goodness may become heavy. However, in the scales of the believer there will be the weight of Faith as well as the weight of the good deeds which he performed in the world. On the other hand, every evil done by him will be placed in the scale of evil deeds and then it will be seen whether his scale of the good deeds is heavier or his scale of the evil deeds.
