Brother, Not to start an argument here but i think thats a valid question… As a muslim we shld know that Prophet s.a.w would never marry his daughters well if u ask my belief. I dont believe that Prophet s.a.w. would ever marry a muslim girl to a non-beleiver. So if someone raises question on how could Prophet s.a.w marry his daughters to non-believers its not judging Prophet s.a.w but judging a muslims believe…how can u read something or hear something that absurd and believe it without thinking about it ?
