Hazrat Tawus says that if a person marries a woman, that woman does not become lawful for his father, whether he has had marital relations with her or not. And similarly, she does not become lawful for his son, whether he has had marital relations with her or not.

Hazrat Zuhri says that if a person marries a woman, that woman becomes forbidden for his son and father. Similarly, if either of the two sees the private part of a woman, she also becomes forbidden for the other.

Hasan was asked: If a man marries a woman and divorces her before consummating the marriage, can that man's father marry that woman? He declared it disliked and recited this verse of the Holy Qur'an { وَحَلاَئِلُ أَبْنَائِکُمْ }

Hasan and Muhammad say that three verses are ambiguous { وَحَلاَئِلُ أَبْنَائِکُمْ } B{ مَا نَکَحَ آبَاؤُکُمْ } C { وَأُمَّہَاتُ نِسَائِکُمْ } Hazrat Ash'ath says, and this D fourth verse is not ambiguous { وَرَبَائِبُکُمَ اللاَّتِی فِی حُجُورِکُمْ مِنْ نِسَائِکُمْ } The narrator Hazrat Mu'adh recited this verse to the end.

16993 - (Al-Ash'ath) said (1): And this fourth one is not ambiguous: "And your stepdaughters who are under your guardianship, born of your wives..." [النساء: ٢٣] , so Mu'adh recited it to its end.

Ibrahim says that if a man marries a woman but does not have conjugal relations with her, even then she is not lawful for his father.
