wouldn't it be the same as marrying the people of the books but why i've seen lots of fatwas it is permissible whereas in malaysia is not allowed. lol i'm sorry if off topic but i had to and i don't think i deserve for a new thread. i would not able to answer all the questions.
Yes you are correct which is why many scholars have stated that it is not permissable for a man to marry a woman who is just Jewish or Christian by name and not by faith and practise. Clearly the Jewish and Christian women of today are very different from the Jewish and Christian women of the time of the Prophet (Sallallahu Alaihi Wasalam).
In order to marry such women then they have to be practising and believing and not athiest as many are nowadays. How many Muslim men of today marry a woman who is just Christian or Jewish just by name? Many do not even believe in God let alone their own religion.
Also one has to ensure that ones children will grow up as Muslims. I know so many Muslims who married non practising Christian girls which ended up in divorce and the children are fed haraam and bought up as non believers. It is truly sad to see.
Sheikh Muhammad Ibn Adam states regarding such marriages:
Women who are Christians and Jews merely by name, and do not really believe in any religion, like a large number of people in the west, cannot be termed as people of the book (ahl al-Kitab). They are atheist in reality and it will not be permissible for Muslim men to marry them.
Therefore, one must first make sure that the woman is truly a believing Christian or Jew, and then consider contracting marriage with them.
Thirdly, it should be remembered that the meaning of the permission of marrying Christian and Jewish women is simply that, if a marriage contract was performed with them, it would be valid according to Islam and the children born out of this wedlock will be considered legitimate.
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).
Finally, this permission is only when one is confident that he himself or his children will not be affected by this marriage. In the early days, Muslims were duly equipped with adequate Islamic knowledge and an unshaken commitment towards their religion. As such, there was no risk of the husband being affected by his wife's religion. Rather, the wife would see the glory of Islam, thus enter into the fold of Islam.
Therefore, if a Muslim male is confident that marriage with a Christian or Jewish girl will have no affect on his and his children's Islamic identity and commitment, then there is no bar against such marriages. However, if he is not so confident, he must avoid entering into such marriages.
