1. I know that if someone touches his mother with lust, it will break his parents marriage. I want to know if it is permissible for his (the one who touched his mother with lust) children/grandchildren to marry his brother’s/sister’s children/grandchildren? Are their children/grandchildren allowed to marry each other?
2. Can he (the one who touched his mother with lust) marry his mother’s brother’s daughter?
3. If the thought comes to mind that a perosn touched his mother with lust during his childhood, but he is in doubt whether he touched or not. What should he do now?
3. He should not pay attention to doubts.
And Allah Ta’ala (الله تعالى) knows best.
