Surah 52. At-Tur, Ayah 21

Implying that the righteousness of their children increases the merit of the parents.

I.e., the righteousness of the parents cannot absolve their offspring from individual responsibility.

 Meaning, no one will carry the burden of another’s sins.

Zurriyat: literally, progeny, offspring, family; applied by extension to mean all near and dear ones. Love is unselfish, and works not merely, or chiefly, for Self, but for others; provided the others have Faith and respond according to their capacities or degrees, they will be joined together. Even though on individual merits their rank might be less.

As already explained in the last note, though the love poured out by Prophets, ancestors, descendants, friends, or good men and women, will secure for their loved ones the enjoyment of their society, it is an indispensable condition that the loved ones should also, according to their lights, have shown their faith and their goodness in deeds. Each individual is responsible for his conduct. In the kingdom of heaven there is no boasting of ancestors or friends. But it is part of the satisfaction of the good ones who poured out their love that those who were in any way worthy to receive their love should also be admitted to their society, and this satisfaction shall in no way be diminished to them.
