“And We will remove whatever disappointment is in their chests, they will be sitting as brothers facing each other”.
For the forerunners who will enter the Paradise without Trial will have no disappointment and hate against anyone. They will have whatever pleasures they wish in the Paradise as told in verses 56: 10-26. But those who enter Paradise after Trial may have little hate and disappointments against one another in their hearts. That is why it is told in verses 84: 7-10: “Then as for he who is given his Recorded Book in his right hand, he will have an easy Judgment; and he will return to his family in rejoicing”. It is told in verses 56: 27-38: “The companions of the right hand have the Sidra trees, clustered bananas, extended shades, constantly flowing water, fruit in abundance which is neither limited nor forbidden and chairs which are raised high; indeed Lord has produced their spouses in a new creation and made them virgins, beloved and of equal age”. See explanation 7: 43; 8: 63-64 and 9: 71-72.
