That was a community that has already passed away, they have whatever they earned, and you will have whatever you earned, and you will not be questioned about what they were doing.
This verse is repeated in verse 2: 141. Every soul is responsible for his/her destiny. So, one has to prepare Paradise in this 4th phase of life to inherit It in the 7th phase in the Hereafter. The children will not be questioned about their parents. But the parents will be questioned about their children. Therefore, it is the duty of parents to teach their children Adhikr mentioned in verse 16: 44 before their fifteenth age, so that they can live here by utilizing Adhikr as the Ticket to Paradise. Otherwise, the parents and children will witness and argue against each other in Hell as told in verse 7: 38.
It is told in verse 52: 21: “We shall unite together the believers and their offspring who followed them with faith, We will not deprive anything of their deeds, everyone is a guarantee for whatever he earned”. Read together 74: 38-39. It is told both in verses 13: 23 and 40: 8 that the believers shall get their righteous offspring, parents, and spouses in Paradise.
What should the believer do to get his parents in Paradise who had died before getting Adhikr? The answer is: ‘After becoming believer by testifying Adhikr he has to propagate Lord’s Message to entire mankind especially to those who didn’t receive It, do and encourage others for planting trees and organic farming aiming to get a portion of the righteous deeds, and the glorification and praising of creatures to his parents testifying verses 2: 261 and 4: 85’.
The Arabic Quran reading Fujjar have read in verse 2: 286: “For the soul has what it earned and upon her what not earned”. That means the people of the last Messenger who didn’t earn the Paradise in this world will get the Hell in the Hereafter which is not earned by them intentionally. See explanation 2: 25, 128, and 25: 67-68.
