[Pooya/Ali Commentary 64:9] The day of judgement will be a day of gain to the righteous and loss to the stiff-necked evildoers and oppressors. Those who collected riches by wrong doing will find themselves paupers, all their efforts wasted, see commentary of Kahf: 104. On the other hand those believers who are considered meek and described as have-nots in this world will acquire honour, dignity and eternal happiness. See commentary of Furqan: 70. Allah will blot out their faults, mistakes and shortcomings and remove their sorrows, sufferings and disappointments. When a sinner turns repentant to Allah and resolves to amend and do good and does so, his past is forgiven and he is transferred from the abyss of degradation to the height of honour. The word taghabun is derived from ghaban which means overcoming in selling or buying. Here it is used to compare the worth of gains the righteous will obtain and the loss the evildoers will suffer. It is said that every believer will enter paradise after he sees the place he would have been allotted in hell if he had not believed and done good deeds; and every disbeliever will see the place in paradise he would have been given if he had believed and done good deeds before going to hell. Aqa Mahdi Puya says: Every man is judged in view of his deeds concerning his self as soon as he dies, receiving rewards for good deeds or punishment for evil deeds; but for his deeds affecting social and collective life the final and abiding judgement will be made after the resurrection. He who has been commanded for his individual shortcomings may be forgiven on the day of judgement in the light of his obedience to divine laws in his social and collective life. Since the abiding loss or gain the day of judgement is described as the day of mutual loss or gain-yawmut taghabun.
