Muslim woman marrying a catholic man

According to Islamic Shariah, a Muslim woman is not permitted to marry a non-Muslim man, even if he is Catholic.

Qur’an:

وَلَا تُنكِحُوا الْمُشْرِكِينَ حَتَّىٰ يُؤْمِنُوا

“And do not marry your women to polytheistic men until they believe.”

(Surah Al-Baqarah 2:221)

More explicitly:

لَا هُنَّ حِلٌّ لَّهُمْ وَلَا هُمْ يَحِلُّونَ لَهُنَّ

“Those women are not lawful for them, nor are those men lawful for them.”

(Surah Al-Mumtahanah 60:10)

Therefore, marriage to a Catholic man would only be possible if he genuinely accepts Islam, after which the marriage can be conducted according to Islamic law.

And Allah knows best.
