People when conducting business giving measure of items they sometimes some of them cheat and defraud by when giving measure it is deficient or not full measure and when wanting some item for themselves demand full measure with some extra on top of it.
This is an imbalance in equity and justice in conducting trade and an entire nation, the nation of the Prophet Shoaib upon him be peace were destroyed due to not giving full measure and defrauding in business.
Allah SWT says to measure correctly with a just and straight balance giving full measure and not to be deficient in giving the due proportion. Allah SWT warns and threatens the people stating do you not think you will be resurrected for a tremendous day in which all accountability will be determined. A heavy difficult day when all of humanity will stand before Allah SWT.
The evil wicked doers the criminals and the oppressors their deeds are being recorded in a place called sijjin which is an eternal prison beneath the seven earths a place of torment and punishment of the hellfire and what will make people realise that sijjin is a place where the fate of the evil doer is already sealed.
So those that deny especially the denial of the day of judgement and no one denies it except every evil transgressor that is bound for sijjin.
When the verses of the Quran are recited to them they claim these are ancient fables or tales, the reason being there hearts cannot fathom the understanding or realization of the words sue to the evil they commit. The heart comprehends only when its purified whereas living an evil sinful life clouds the heart with darkness not allowing a person to delve into the sublime knowledge and understanding of the verses of the Quran, due to their evil doing they will be sealed off on the day of judgement unable to see Allah and moreover they certainly burn in hellfire for the evil they used to commit.
Due to denying this reality it will be said to them on this day of reckoning, this is what you sued to deny or earth and terrible will be the punishment of the hellfire inflicted upon them. As for the believers who work good and do righteous deeds seeking Allahs favour and reward their deeds are being recorded in a place called illiyeen, which is a part of paradise in elevated gardens and what do people think and realise about illiyeen is that it is a place for souls of the believers where their fate is already sealed and determined according to the good they used to do upon the earth. The people of virtue will be in a state of bliss in paradise as they will have attained forgiveness and mercy from Allah SWT and be placed into the gardens where they will have canopied couches on which they will be seated looking around at the blessings and beauty of the environment of the gardens of paradise. They will be recognized with a bright light glowing from their faces with delight and given to them will be a specific drink of paradise called Rahiq which is sealed pure wine that neither intoxicates and does no harm but is a delight and enjoyable drink whose scent of the wine will be like musk so fragrant and let the people aspire to diligently strive for this blessed drink that will only be rewarded in the gardens of paradise and the flavour of the drink will come from a spring known as Tasnim which will be mixed with the Rahiq the sealed pure wine and those believers who are very close to Allah will enjoy the delight of the drink.
Allah SWT mentions how on the earth the evil wicked doers would laugh at the believers and wink to one another when passing by and when returning to their own people would talk and muse over their exploits of demeaning and making the believers and would claim about the faithful believers that these people are astray even though they are not sent as keepers over the believers. The promise of Allah that the disbelievers and evil wicked doers will realise when on the day of reckoning judgement will be passed on them and for certainty they will be punished in the hellfire and the believers will be rejoicing and laughing from their place in Jannah where it will be shown to them the terrible state of the disbelievers and the disbelievers will have been paid back for what evil they used to do as the recompense for evil is the punishment of the hellfire an evil destination.
The believers will be asked about this and they will thank and praise Allah SWT for saving them from the torment of the fire and they will be rejoicing in the blessings and delights of the gardens of paradise.
