The short answer, from an Islamic standpoint, is no—it is not permissible. Here's why:
1. Islam Emphasizes Truthfulness in All Matters
One of the fundamental teachings in Islam is truthfulness. The Prophet Muhammad ﷺ stated:
Hiding one's religious identity in order to gain approval for marriage is considered deception, which is clearly discouraged in Islam. A marriage built on dishonesty risks not only religious consequences but also emotional and legal damage in the long term.Truthfulness leads to righteousness, and righteousness leads to Paradise. A person who consistently speaks the truth will be recognized as truly honest. On the other hand, lying leads to corruption, and corruption leads to the Hellfire... — (Sahih al-Bukhari
2. Marriage Has Spiritual and Legal Conditions in Islam
Islamic law lays down clear guidelines for marriage:
(a) Muslim men are permitted to marry women from the People of the Book (Christians and Jews), provided they do so with transparency and respect.
(b) Muslim women, however, are generally not permitted to marry non-Muslim men unless the man accepts Islam.
In either case, hiding religious identity invalidates the honesty required in the marriage contract (nikah) and could make the union Islamically invalid.
3. Religious Identity Is a Core Part of a Muslim’s Life
Islam is more than just a name—it is a complete way of life. Deliberately concealing one’s faith for worldly benefits or personal comfort contradicts the true spirit of being a Muslim. As Allah says:
This verse, though contextually about hiding revelation, reflects the serious nature of concealing truth, especially one’s religious identity.Indeed, those who conceal the clear signs and guidance We have sent down are cursed by Allah and by those who invoke curses. — Surah Al-Baqarah (2:159)
4. A Relationship Built on Faithlessness Breeds Doubt
Marriage in Islam isn’t just about romantic love—it’s a partnership in faith. When one partner hides their true beliefs, it raises fundamental concerns about trust and long-term compatibility. Even if the marriage survives socially, it may fail spiritually, affecting both partners and future children.
In Islam, marriage is founded on sincerity, faith, and mutual respect. Hiding one’s Muslim identity in order to marry someone from another religion is not allowed, as it involves deception and goes against the core values of an Islamic marriage.
If someone is serious about marrying a person of another faith, the right path is through open conversation, mutual respect, and if necessary, religious guidance—not through hiding one’s identity.
Upholding faith while being honest may not always be easy—but in the long run, it leads to blessings, peace of heart, and Allah’s pleasure.
