Should the call to Islam for married women be abandoned for fear of their families breaking up, while their faith might initially be weak, keeping in mind that there are fatwas considering this matter illogical?

Calling to Allah is an obligation upon the Ummah, and it is directed to all people without discrimination, while observing wisdom, good admonition, and gentleness. If the wife converts to Islam while her husband remains in disbelief, she is not permitted to allow him to have conjugal relations with her. It is best to clarify the ruling to the maidservant: that her husband has more right to her if he converts to Islam, and that she has more right to her children than him if he remains in disbelief, while encouraging her towards the virtues of Islam.
