Marrying a Christian woman is allowed but it is better to choose a Muslim wife when possible.The father is obligated to raise the children properly in such a way that they become believers, perform the obligatory deeds and avoid committing the prohibitions. It is better to choose correct and effective ways in their upbringing so they may be more inclined towards the true religion. Almighty Allah says: "O ye who believe! Ward off from yourselves and your families a Fire whereof the fuel is men and stones."(Quran 66:6).
