Musannaf Ibn Abi Shaybah

Hasan, Hazrat Ikrimah, and Hazrat Umar bin Abdul Aziz (s) state that if either the husband or wife among the Magians accepts Islam, the man no longer has any right over the woman without a new marriage proposal.

Hasan (may Allah have mercy on him) said that if either husband or wife among the Magians accepts Islam, then their marriage is annulled.

It is narrated similarly through another chain.

Hazrat Ata (may Allah have mercy on him) says that if a polytheist man and woman accept Islam together, their marriage will remain intact, but if only one of them accepts Islam, their marriage will be annulled. This ruling applies to Magians and polytheists, not to the People of the Book.

Hazrat Hakam (may Allah have mercy on him) says that if one of the Magian husband and wife accepts Islam, separation will be established between them.
