Avoiding people who have children because one does not have children
Q: Is it against rada bil qada to not associate with people who have something you desire. E.g. Avoiding people who have children because you do not have or avoiding friends who are married because you are unmarried?
A: There is no need to avoid such people. It is not in accordance to the sunnat to avoid people for such reasons.
And Allah Ta’ala (الله تعالى) knows best.
