When you convert from Islam to Christianity, all the Muslim women become your sisters. And being a true Christian, you must never marry a Muslim woman. Shall a Muslim girl ask you to marry her, you must first demand her to become Christian. It is a rule that they created for us, then it is a rule that we’ll honor and follow.
It is shameful, for a Muslim man to tell a Christian who converted from Islam, to marry a Muslim girl. But it is more shameful for the newly converted Christian to touch a Muslim woman, knowing one can’t marry in the faith that one left..
This is a verdict of faith, that’s worth following.
Update: I withdraw from this verdict. Otherwise, what’s the difference between us and them. They are tone-deaf when it comes to faith, so they’ll ask you where does in Bible Jesus said I’m God worship me, but when you’ll ask them where in Quran does Mohmad said I’m prophet send me Naat, Darood-o-Salaam, they’ll go answerless. They certainly have nothing but lies to explain, what Q:46:9 has to say. Among religions, they are the only ones who do not understand, do not do unto others what you wish not be done unto thyself, the golden rule of prophets of Bible.
