If a Muslim boy is in love with a non-Muslim girl and it is time for marriage. The girl agrees to convert. Will the boy get Sawab for converting a non-Muslim to a Muslim or will he be punished for having an affair with a non-Muslim?
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 is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
In principle it is not permissible for a Muslim man to establish a relationship with a marriageable woman even if she is a Muslim, let alone if she is not a Muslim. If the woman is not a Muslim, the matter is more serious as she could influence him by this relationship and lead him to apostate from Islam. So whoever is involved in such a relationship should repent to Allaah. Moreover, it is a woman who should call another woman to Islam to avoid being tempted by her, and women can understand each other better. However, if there is a need for a man to call her to Islam, then there is no harm provided that the religious requirements are met, like not being in seclusion with her, avoid forbidden looking and the like. If it happens that a man has a relationship with a marriageable woman then he is sinful unless he repents. But if he calls her to Islam during that relationship and then she embraced Islam, then he will get the reward for her embracing Islam. The Prophet said: "Whoever calls for any act that leads to the right path gets a reward similar to all the rewards that the people who followed him get. This does not reduce anything from their (the people’s) reward." [Muslim] Finally, we stress on what we have first mentioned that it is not permissible to establish such a relationship.
Allaah knows best.
