Praise be to Allaah.
The fuqaha’ differed concerning one who commits zina with a
woman: is it permissible for him to marry her daughter or not? There are
The Hanafis and Hanbalis are of the view that it is not
permissible for him; they regarded haraam intercourse as being like halaal
intercourse with regard to who becomes a mahram as the result of a
The Maalikis and Shaafa‘is are of the view that he may marry
Ibn Qudaamah (may Allah have mercy on him) said: Haraam
intercourse creates the same mahram relationships as halaal intercourse or
intercourse as the result of a dubious marriage - meaning that those who
become mahrams as a result are confirmed in all three cases. So if a man
commits zina with a woman, she becomes haraam to his father and son, and her
mother and daughter become haraam to him. Something similar to that was
narrated from ‘Imraan ibn Husayn, and this was also the view of al-Hasan,
‘Ata’, Tawoos, Mujaahid, al-Sha‘bi, al-Nakha‘i, al-Thawri, Ishaaq and ashaab
Ibn ‘Abbaas narrated that haraam intercourse does not make
anyone a mahram. This was also the view of Sa‘eed ibn al-Musayyab, Yahya ibn
Ya‘mir, ‘Urwah, al-Zuhri, Maalik, al-Shaafa‘i, Abu Thawr and Ibn al-Mundhir.

mother and being in touch with her, and there is the fear that this would

cause of the woman (the mother) being tempted. We ask Allah to keep us all
safe and sound.
If your friend is in a relationship with this man, this
indicates that he is corrupt and deviant, as he did not have any religious
commitment that could have deterred him from committing zina with a woman
who had three children and forming a relationship with her daughter. Such a
man cannot be trusted at all. Your friend has to end her relationship with
him. Perhaps Allah will send her a chaste husband who is not contaminated
with this evil and sin.
And Allah knows best.
