Question:
salam,
Can a father forbid his son to marry a Christian woman just to treat his son and daughter equal since she can just marry a Muslim and because in Shafi school non-Israelite Christians (almost all nowadays) are not considered ahl kitab?
Answer:
Alaykum Salam,
A father may forbid his son to marry a woman the father considers an unfit spouse for his son regardless of her being a Muslim or not.
