Could you please state the area in the quraan or hadith clarifying this? Thank you.
It is not permissible for a Muslim male to marry a non-Muslim female. The
ruling excludes marrying a female from the Ahle-kitaab (Christians and
Jews). Kindly refer to marriage to the Ahle-kitaab on this site.
The beliefs of the shias are inconsistent with the fundamental beliefs of
the Ahlus Sunnah wal Jamaa’ah, therefore they are not Muslims. Kindly refer
to the beliefs of the shias on this site .
And Allah Ta’ala Knows Best.
