Peace be upon you. According to Ayatollah Khamenei (may Allah protect him), marriage to someone from a differing sect—whether permanent or temporary—is not permissible if there is a fear of danger to her beliefs or if it leads to corruption. It is required for a virgin girl to have the consent of her father or paternal grandfather, as a precautionary obligation.
According to Ayatollah Sistani (may Allah protect him), a believer may marry someone from a differing sect who is not an open enemy (nasibi), and a believing woman may marry a non-nasibi man in a permanent marriage, albeit with disapproval. However, it is forbidden if there is a fear that it may lead to deviation in faith or prevent the performance of religious duties according to the Imamite sect. Temporary marriage is permissible if the non-believer believes in the validity of this marriage according to their sect.
For marrying a virgin girl, the consent of her father or paternal grandfather is required unless she is independent in her affairs, in which case it is advisable to obtain the consent of one of them if she is independent.
May you be successful in all good things.
