The Ruling on a Sunni Marrying a Shi'i

Question:
What is the ruling on a Muslim from the people of the Sunnah and the community marrying a Shi'i?

Answer:
It is not permissible for one to marry a Shi'i; because among the Shi'ah are those who worship 'Ali, seek aid from the Ahl al-Bayt, associate partners with Allah through them, and call upon them other than Allah. This is major shirk (associating partners with Allah), especially the Shi'ah that exist today, in most of the world, who are predominantly characterized by exaggeration regarding the Ahl al-Bayt.
Therefore, what is required of the people of the Sunnah is not to marry from them unless it is known that she is not upon the religion of her people, and that she has entered into the Sunnah, and is upright upon the Sunnah, and has distanced herself from the exaggeration of her people regarding the Ahl al-Bayt. For they exaggerate regarding the Ahl al-Bayt, and call upon 'Ali other than Allah, and al-Husayn and Fatimah, and seek aid from them. Even a woman at the time of divorce says: "O 'Ali!" except for those among them whom Allah wills, except for those among them whom Allah guides. One should be careful in these matters. We ask Allah for guidance for us and for them.
