I pray that your daughters boyfriend is with her for the ‘right’ reasons…
(and not for a quick passport to the UK) Unfortunately, I saw much of this before I emmigrated…
I read the qur’an some 30 yrs ago, I was in the same University college in Wales as a lot of Lybians… I grew to have a healthy ‘respect’ for most of them… As with Bolyen’s comments I too personally believe they are misguided in their beliefs and they are nothing more than ramblings… Although I think there was a little Demonic oppression thrown into the mix!!
I learned to speak some Arabic, and more importantly to count in Arabic… *(used to play Table Tennis with them… and they really didn’t like me ‘a woman’ beating them

so they would try and confuse me by keeping score in Arabic… and then tell me it in English.). *After thinking H’mmm I thought I should have won … I learnt to count !!
During Ramadan, I was invited and participated in their breaking of fast!! Oh what great food!!
Many of these Muslims gave me Christmas Cards, some even bought me gifts, they had no problems saying Merry Christmas… Boney M was in the charts at the time, most would be going round singing ‘Mary’s Boy Child Jesus Christ was Born on Christmas Day’ When I asked them about this … The response was… Jesus was a good and Holy Man, we don’t think he was the Son of God, but some 'minor Prophet… Jesus was a good Man so his mother was too, we are taught to love and respect our Mothers…
So not all Muslims are extremists, many albeit misguided ~ believe they are on the right path and like us aspire to lead good and decent lives… I did fall for one of them…We had many a discussion of Faith, however I finally turned my back when I realized that the faith issue was something neither of us could cross…
