A disbeliever who embraced Islam and had children on the religion of Islam; what is the ruling on his remaining in the land of disbelief?

The questioner : Our Shaykh, a disbeliever embraced Islam and had children on the religion of Islam; what is the ruling of the Shari'ah regarding their remaining in disbelief, O our Shaykh?

The Shaykh : Remaining in disbelief or in the land of disbelief?

The questioner : The land of disbelief, yes.

The Shaykh : By choice or by necessity, may Allah forgive you?

The questioner : By Allah, O our Shaykh, as far as I know, he was originally a disbeliever.

The Shaykh : I know, but do these children remain by choice or by necessity?

The questioner : Of course by necessity, with their father, O Shaykh.

The Shaykh : Then they are not asked if it is out of necessity.
Peace be upon you.
