He committed zina with a woman; is he allowed to marry her daughter?
Question

                I am a thirty year old man. The shaytaan tempted me and I committed zina with a woman, then Allaah blessed me and had mercy on me, and I repented sincerely to Allaah, may Allaah accept it from me. Until now I have not gotten married. I have decided to get married and my mother has suggested a girl, but this girl is the daughter of the woman with whom I committed zina before (please note that the zina occurred two years ago, and her daughter is now twenty years old). Hence I hope that you can advise me whether this marriage is haraam or not? I hope that you can explain fully.
Praise be to Allah.We ask 
    Allaah to accept your repentance. Strive to make it a sincere repentance, 
    because the crime of zina is a grave sin which results in many evils. The 
    married man who commits zina deserves to be stoned to death, and there is no 
    greater punishment than that among the hudood punishments, because of the 
    abhorrent and repugnant nature of this crime. 
Our advice 
    to you is not to marry this girl, not because marrying her is haraam, but 
    because through this marriage you will become closer to her mother with whom 
    you committed zina, and getting close to her will remind you of that evil 
    sin, and the shaytaan may whisper to you again, and make sin appear 
    attractive to you, so you fall into it. Keeping away from reminders of evil 
    and sin is part of repentance. This is indicated by the hadeeth about the 
    one who killed one hundred people; the scholar told him to leave his village 
    because its people were evil and immoral people. This is part of repenting 
    fully. 
With regard 
    to whether it is permissible to marry this girl, there was a difference of 
    opinion among the scholars regarding such cases. Al-Shaafa’i and Maalik – 
    according to one of the two reports narrated from him – said that it is 
    permissible, but Abu Haneefah, Ahmad and Maalik – according to the other 
    report – said that such a marriage is haraam. The more correct is the first 
    view. 
Ibn ‘Abd 
    al-Barr said: 
They 
    differed concerning a man who commits zina with a woman; is it permissible 
    for him to marry her daughter or mother? Similarly, if he committed zina 
    with a woman, can his son or father marry her? In all these cases, does zina 
    make haraam what a valid marriage or an invalid marriage makes haraam (i.e., 
    makes certain relatives mahrams to whom marriage is forbidden)? 
Maalik said 
    in his Muwatta’: Zina with a woman does not make it haraam for the 
    one who commits zina with her to marry her daughter or mother. If a man 
    commits zina with the mother of his wife, his wife does not become haraam to 
    him, rather he should be killed. Zina does not make haraam anything that a 
    permissible marriage makes haraam. 
This is the 
    view of Ibn Shihaab al-Zuhri and Rabee’ah; it was also the view of al-Layth 
    ibn Sa’d, al-Shaafa’i, Abu Thawr and Dawood. It was also narrated from Ibn 
    ‘Abbaas, who said concerning that: A haraam deed does not make something 
    permissible haraam. 
Ibn 
    al-Qaasim narrated from Maalik something other than what is said in 
    al-Muwatta’. He said: If a man commits zina with the mother of his wife, 
    he must be separated from his wife, and in his view he comes under the 
    ruling of one who has married his wife’s mother and consummated the marriage 
    with her. This is also the view of Abu Haneefah and his companions, and of 
    al-Thawri and al-Awzaa’i, all of whom said that if a man commits zina with 
    his wife’s mother, then his wife becomes haraam for him. 
Sahnoon 
    said: The companions of Maalik all disagreed with Ibn al-Qaasim on this 
    matter and they agreed with what it says in al-Muwatta’. Allaah has 
    forbidden the Muslim to marry his wife’s mother or daughter. If a man owns a 
    slave woman and he has intercourse with her, then her mother and daughter 
    also become haraam for him. 
Similarly, 
    if his father has intercourse with a woman whom he marries or owns as a 
    slave, they become haraam for the son, and vice versa. This has to do with 
    permissible types of intercourse. And Allaah is the One Whose help we seek. 
     
These 
    fuqaha’ – the ones who were qualified to issue fatwas in the Islamic regions 
    – were unanimously agreed that it is not haraam for a man to marry a woman 
    with whom he committed zina, if it is established that she is not pregnant, 
    so it is more likely that he is permitted to marry her mother or daughter. 
    And Allaah is the source of strength.

    (5/463, 464). 
Shaykh 
    Muhammad ibn Saalih al-‘Uthaymeen (may Allaah have mercy on him) said: 
The correct 
    view is that the mother of a woman with whom a man has committed zina is not 
    haraam for the one who did that, and the daughter of the woman with whom he 
    committed zina is not haraam for the one who did that, because Allaah says 
    (interpretation of the meaning): 
“All 
    others are lawful”
[al-Nisa’ 
    4:24]
Allaah did 
    not mention the mother or daughter of a woman with whom zina has been 
    committed as being among those to whom marriage is forbidden, rather He 
    said:  
“your 
    wives’ mothers, your stepdaughters under your guardianship, born of your 
    wives to whom you have gone in — but there is no sin on you if you have not 
    gone in them (to marry their daughters),”
[al-Nisa’ 
    4:23]
It is well 
    known that the woman with whom a man has committed zina is not one of his 
    wives at all. As she is not one of his wives, it is not valid to compare 
    fornication to valid marriage. If he has repented from zina it is 
    permissible for him to marry the mother or daughter of a woman with whom he 
    committed zina. End quote.

Conclusion: 
This is a 
    matter concerning which the scholars differed. The correct view is that it 
    is permissible to marry the daughter of a woman with whom one has committed 
    zina so long as she is not one’s own daughter, but our advice to you is 
    not to marry her for two reasons: to be on the safe side, because she is 
    haraam for you according to many of the scholars, and so that your marriage 
    to her will not be a cause of your getting close to her mother and getting 
    in touch with her, which may lead to you going back to that sin from which 
    you have repented. And Allaah knows best.
