All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
First of all, you must sincerely repent to Allaah from that forbidden relationship; the conditions of a sincere repentance are already mentioned in Fatwa 86527, so please refer to it.
Whoever sincerely repents, Allaah accepts his repentance even if he/she has committed great major sins. Allaah Says (what means): {Say, “O My servants who have transgressed against themselves [by sinning] do not despair of the mercy of Allaah. Indeed, Allaah forgives all sins. Indeed, it is He who is the Forgiving, the Merciful.”}[Quran 39:53] Hence, you should take the initiative to repent and think good of your Lord.
On the other hand, we did not understand what you meant by Allaah answering your tears; if you mean regretting and repenting, then a true repentance is of course accepted by Allaah as we have already discussed.
Secondly, you are not sinful - Allaah willing – if we presume that that woman misused the translation of the Quran which you had given her because you gave it to her with a good intention, which is that she benefits from it.
Thirdly, it is not permissible for you to curse her personally; according to the preponderant opinion of the scholars cursing a particular non-Muslim is not permissible as we discussed in Fatwa 88954.
Fourthly, how can you authoritatively assert that she will be punished after death? It might be that Allaah will guide her and she would embrace Islam, and Islam wipes out all previous sins as confirmed in a Hadeeth reported by Muslim .
Besides, what would be your benefit if you see her being punished? Instead of this, ask Allaah to guide her [to Islam] and enable her to repent.
Finally, it might be that you would take a lesson from this illicit relationship and not do that again. Also, you should be vigilant not to be deceived by what you were deceived by in the past.
Allaah Knows best.
