Yep your marriage (Al Hamdullah) is a great example of introducing potentially compatible people for marriage...then giving them the CHOICE.

I introduced two friends of mine over the internet
a) one mexican
b) one south african
both in their respective countries
they an now happily married with a gorgeous daughter...
Mashallah.
So I arranged the hook up and introductions....they chose.
Same thing.
I was so happy to be the ring bearer at their wedding.

my best friend now owes me a husband ;)
