I will clear my standpoint. I am a secular, so I have no problem with such a marriage or a person converting to Islam for whatever reason. People can do whatever they want.
But, I am a Muslim, and I don't like it if some people twist religion to suit them better. Sure, you want to marry a non Muslim, do it, but don't find loopholes in your religion to do so. And if they do use loopholes, others shouldn't seek to justify it when it is religiously wrong.
1. Someone said that they might become actually practicing Muslims in the future. Yes, but so might people who were forced to convert; does it make it right? Absolutely not. In Islam, it's not just about the end result, but also about the path you take, it must be religiously allowed. You can't make drug money and use it to build a mosque. In the end, she converted for 'him,' and that isn't a conversion. You convert for Allah, not your boyfriend or girlfriend. So stop trying to say that it is right. It isn't.
2. Giving people money to convert is also wrong. You can give charity and HOPE that they will see the good and convert, but setting it as a pre condition for better life is wrong. Again, reasoning in point 1.
3. I won't say force her to go back, bla bla. No, she can do what she want. I am just saying that you guys need to stop painting something as right from the Islamic viewpoint when it is absolutely wrong from an Islamic viewpoint.
You know what this reminds me of. When in britian, some muslim women found a loophole in Islam to do prostitution, they would marry a man who wanted to have sex, have sex, then do talaq, and then onto the next client.
I see this in the exact same way. Coversion is for God's sake, and truly, we don't know what's in their hearts or their intention, we ought to give the benefit of doubt, but when she DECLARES her intention (she converted for 'him' i.e. so she could marry him), then it is wrong in Islam, and you folks need to have an ounce of shame when your justifying this and saying it is Islamic and STOP SELLING YOUR RELIGION FOR SEX and MONEY.
Thank you.
