﴿ وَٱلَّذِينَ ءَامَنُوا۟ وَٱتَّبَعَتْهُمْ ذُرِّيَّتُهُم بِإِيمَٰنٍ أَلْحَقْنَا بِهِمْ ذُرِّيَّتَهُمْ وَمَآ أَلَتْنَٰهُم مِّنْ عَمَلِهِم مِّن شَىْءٍۢ ۚ كُلُّ ٱمْرِئٍۭ بِمَا كَسَبَ رَهِينٌۭ ﴾

“And as for those who have attained to faith and whose offspring will have followed them in faith, We shall unite them with their offspring; and We shall not let aught of their deeds go to waste: [but] every human being will be held in pledge for whatever he has earned.”

In the Hereafter, it will not happen that one man’s sins are attributed to another, and nobody will be able to enter Paradise except on the basis of his faith and his own righteous deeds. But, the occupants of Paradise will be given one special privilege: if parents are in a high stratum of Paradise and their children in some other stratum, the children will be united with their parents so that their happiness should increase. Only one who, in spite of being among his wife and children, has always been moved by the fear of God and who linked his hopes and fears with the one and only God, will be entitled to enter the sublime world of Paradise.
