Wa Alaikum Assalam,Your question is very serious and intellectual in nature, and it is not merely an emotional objection but an attempt to understand the issue at a principled level. In Islamic jurisprudence, the marriage of a Muslim woman to a non-Muslim man is considered impermissible, and there is near consensus among classical and contemporary scholars on this matter. This ruling is based primarily on Qur’anic texts, particularly Surah Al-Baqarah 2:221 and Surah Al-Mumtahanah 60:10, where believing women are not declared lawful for disbelieving men.This issue is not limited only to historical social structures where men held religious dominance, although that aspect is sometimes mentioned as a wisdom behind the ruling. The core basis is not social custom but principle. In Islam, marriage is not merely a private relationship between two individuals; it is a contract that affects lineage, upbringing, religious identity, and the structure of the family. Islam designates the husband as qawwam, meaning the one responsible for and maintaining the household. If the husband does not accept Islam as the ultimate truth, then the woman would practically be living under a framework whose ultimate loyalty differs from Islam. Even if he is respectful and not hostile toward Islam, belief in Islam is not merely about moral behavior; it involves acknowledging ultimate truth and authority.As for the possibility that such a person might later accept Islam, Islamic law does not suspend its rulings based on possibilities. If he sincerely accepts Islam, then there would be no barrier to marriage. However, one cannot permit a prohibited marriage on the assumption that conversion may occur in the future. Similarly, the argument that societies have changed today does not override clear textual rulings, because Islamic laws are not dependent solely on shifting social structures but are grounded in enduring principles.It is also important to understand that Islam does not prohibit such a marriage by declaring it morally evil in a personal sense; rather, it considers it legally impermissible. A non-Muslim man may possess excellent character, responsibility, and good conduct. However, faith is established in Islam as a foundational criterion, because marriage shapes not only worldly compatibility but also one’s direction in the Hereafter.Your question essentially concerns fairness and balance: if Muslim men are permitted to marry women from the People of the Book, why are Muslim women not given the same allowance? Scholars have generally responded that, within the marital structure, leadership and family identity tend to be more strongly shaped through the husband. Therefore, the protection of a woman’s faith has been treated as particularly sensitive. This is not a matter of diminishing a woman’s worth, but rather of placing central importance on safeguarding her religious commitment.Ultimately, this issue is not about a lack of reason or moral appreciation, but about adherence to revealed text. If a person accepts Islam as the truth and enters the fold of faith, then there is no obstacle to marriage. However, until he does so, Islamic law does not consider such a union permissible, regardless of how compatible it may appear from a worldly perspective.
