Is it acceptable for a muslim man to marry a christian woman.
Holy Qur'an says,
This day [all] good foods have been made lawful, and the food of those who were given the Scripture is lawful for you and your food is lawful for them. And [lawful in marriage are] chaste women from among the believers and chaste women from among those who were given the Scripture before you, when you have given them their due compensation, desiring chastity, not unlawful sexual intercourse or taking [secret] lovers. And whoever denies the faith - his work has become worthless, and he, in the Hereafter, will be among the losers. [Holy Qur'an 5:5]
no one can attain true life, happiness and peace of mind unless he believes in Allaah as his Lord, Islam as his religion and Muhammad as his Prophet. For all of the universe is created, and its Creator is Allaah. He is the One Who raised the heavens with no pillars and spread out the earth, and created the mountains to stabilize it, and created the sea and the rivers.
“And whoever seeks a religion other than Islam, it will never be accepted of him, and in the Hereafter he will be one of the losers”
A slave woman who believes is better than an unbelieving woman, even though if she attracts you. (al-Baqarah, 221)
The reason behind this is that, marital relationships demand mutual love, affection and intimacy and without this, the purpose of marriage is left unfulfilled. If such close relationship of love and intimacy is established with a non-Muslim, it may emotionally incline a Muslim towards disbelief (kufr) or, at least, the abhorrence of Kufr and Shirk may not remain in the heart. Consequently, it may lead one to disbelief and eventually the fire of Hell. This is why Allah Almighty said towards the end of the verse of Surah al-Baqarah quoted above:
�Unbelievers do (but) beckon you to the fire but Allah beckons by His grace to the garden (of bliss) and forgiveness, and makes His signs clear to mankind; that they may receive admonition�. ( 221). (See: Ma�arif al-Qur�an, 1/ 540).
However, there are various narrations that establish its undesirability. A Muslim man is advised in the Hadith to select a life partner who fully observes the injunctions of Islam, so that she becomes a means of attaining piety. If that is the case, then marrying Christian and Jewish girls would be disliked.
This is the reason why Sayyiduna Umar ibn al-Khattab (Allah be pleased with him) prevented many such marriages in his lifetime because of what he had seen of the corruption that resulted in Iraq and Syria. (See: Muhammad ibn al-Hasan, Kitab al-Athar).
