She repented from a haram relationship in which she lost her virginity. Should she marry who fornicated with her?
Question

                I am in a relationship with a man who took my virginity. I repented from such evil deeds and ask Allah to accept my repentance. This man proposed to me, but he is not religious, he smokes cigarettes and hashish and drinks alcohol. What should I do, he knows my matter. Or shall I leave him and have a hymen repair operation done and marry a religious man? I was pregnant and I aborted the baby. Allah knows how sincere my repentance is.
Praise be to Allah.
    Firstly: 

    Zina 
    (fornication or adultery) is a major sin. Allaah has forbidden doing the 
    things that lead to it and has prescribed the hadd punishment for the one 
    who does it, and He has warned adulterers of punishment in the Hereafter. 

    Allaah says 
    (interpretation of the meaning): 

    “And come 
    not near to unlawful sex. Verily, it is a Faahishah (i.e. anything that 
    transgresses its limits: a great sin), and an evil way that leads one to 
    hell unless Allaah forgives him”

    [al-Isra’ 
    17:32]. 

    Ibn Jareer 
    al-Tabari (may Allaah have mercy on him) said:  

    “And come 
    not near” O people 

    “to 
    unlawful sex. Verily, it is a Faahishah (i.e. anything that transgresses its 
    limits: a great sin)”. Zina (translated here as “unlawful sex”) is a 
    great sin.  

    “and an 
    evil way” i.e., the way of zina is an evil way, because it is the way of 
    the people who disobey Allaah and go against His command; what a bad way is 
    the way that leads a person to the fire of Hell. 

    Tafseer 
    al-Tabari 
    (17/438). 

    Shaykh ‘Abd 
    al-Rahmaan al-Sa’di (may Allaah have mercy on him) said: 

    The 
    prohibition on approaching it is more eloquent than a simple prohibition on 
    doing it, because that includes the prohibition on all the things that lead 
    to it and promote it, because “the one who grazes his flock around a 
    protected areas will soon transgress upon it,” especially in a matter of 
    this nature when the motive is very strong. Allaah describes zina as 
    abhorrent, as He says “it is a Faahishah (i.e. anything that transgresses 
    its limits: a great sin)”, i.e., it is a sin which is abhorrent 
    according to sharee’ah, reason and common sense, because it is a 
    transgression against Allaah, and against the woman and her family or 
    husband, and it leads to immorality, confusion of lineages and other evil 
    consequences. 

    “and an 
    evil way” means: what an evil way is the way of the one who dares to 
    commit this grave sin. 

    Tafseer 
    al-Sa’di 
    (p. 457).

    Secondly: 

    With regard to 
    the abortion, if the soul had been breathed into the foetus, then this is 
    another crime in addition to the crime of zina. If the soul had not yet been 
    breathed into the foetus then it is less serious.

    discussion on that, please see the answers to questions no.

    Thirdly: 

    We praise 
    Allaah for having enabled you to repent, and we hope that it is sincere 
    repentance. The conditions of sincere repentance include: regretting the 
    sins that you have committed, and immediately giving up that immoral action, 
    and everything that leads to it such as contact, correspondence and dates. 
    The conditions of repentance also include resolving not to return to this 
    deed. 

    You also have 
    to do a lot of righteous deeds, such as prayer, reading Qur’aan and fasting, 
    so as to strengthen your faith and piety. Good deeds erase bad deeds and 
    sincere repentance erases that which came before it, and turns bad deeds 
    into good deeds. Allaah says – after mentioning the sins of shirk 
    (associating others with Allaah), murder and zina – (interpretation of the 
    meaning):  

    “Except 
    those who repent and believe (in Islamic Monotheism), and do righteous 
    deeds; for those, Allaah will change their sins into good deeds, and Allaah 
    is Oft‑Forgiving, Most Merciful”  

    [al-Furqaan 
    25:70]. 

    Fourthly: 

    With regard to 
    marrying that criminal, you should understand that in order for the marriage 
    of a man and woman who had committed zina to be valid, it is essential that 
    they repent sincerely. It seems to us from your questions that he has not 
    repented from what he did, rather he had added to the first calamity the 
    other bad things that he is doing, such as smoking hasheesh and drinking 
    intoxicants. What we think is that one who is like this also does not pray. 
    If this is indeed the case, then it is definitely not permissible to accept 
    him as a husband, because not praying is kufr that puts a person beyond the 
    pale of Islam, and it is not permissible for a Muslim woman to marry a 
    kaafir.

    fornication or adultery), please see the answers to questions no.

    96460. 

    Fifthly: 

    With regard to 
    having an operation to repair the hymen, this is haraam, because it is 
    deceiving the one who marries you. 

    For a detailed 
    discussion of this matter, please see the answer to question no.
    844. 

    With regard to 
    telling your future husband that you lost your virginity in this haraam 
    relationship, that is not permissible, because it is exposing your faults, 
    and the Muslim is required to conceal his faults. You can use double 
    entendres in your speech. It is well known that the hymen may be broken by 
    means of something other than intercourse in some cases, so you can make the 
    most of that by using a double entendre. 

    See the answer 
    to question no. 42992. 

    But if it is 
    possible to encourage this person to repent sincerely and pray regularly, 
    and he shows sincerity and signs of repenting and praying regularly, then 
    there is nothing wrong with accepting him as a husband. Undoubtedly this 
    solution would be easier for you, and more concealing for you, but how could 
    one believe a person like that?! 

    We ask Allaah 
    to accept your repentance and set your affairs straight, and to conceal our 
    faults and yours in this world and in the Hereafter. 

    And Allaah 
    knows best.
