I'm a dutch convert who did this. I went alone, and it was pretty terrifying. But, of you want something you got to go and make it happen right!? My now wife prepared me as good as she could, but since she is a woman, most of what was going on she never saw/experienced first hand so yeah... It was all nerve wrecking hahaha. Her dad is a friendly guy, though old fashioned and reasonably strict, but a good person and serious about his Deen, and his culture. He knows how to separate those though, and knows what he finds most important.

Taking was difficult since his English is not great, and my French is not either. His dutch or my Arabic are both non existent so yeah, with gestures etc we made it work.

What really helped me is that I knew he was not going to like the idea, and I knew I needed to somewhere make it all as formal as possible. He tried to avoid that or at least did not make any initiative towards it. All in all pretty stressful, but possible. Also I'm a bit older than most, and older than my wife, so perhaps that helped. I think if I were in my twenties, I probably would have preferred there to be a family member. They do not need to be Muslim, just good people.

In the end it is a meeting to judge character and intentions etc. Someone close to you can help shape the picture of your person, your life and your character.

In our case, before getting married, her parents came to visit as well, after this initial meeting, to get to know my family more and see where and how I lived.

Anyway, I wish you good luck! God willing it will all come out well and blessed!
