What is the ruling on Muslim women who are new to Islam speaking with non-mahram men, and are there explicit legal proofs from the Sunnah and the Pious Predecessors that clarify the regulations and exceptions for this matter?

The Sharia has laid down general rules for the relationship between men and women to achieve benefits and protect both parties from temptation. Among these is the prohibition of speaking in a soft or alluring manner, as stated in His Almighty's saying: (Then do not be soft in speech [to men], lest he in whose heart is disease should covet). Teaching the rulings of Sharia to men is permissible for women, provided that the Sharia-compliant controls are observed. Preachers who fear temptation must avoid direct da'wah (inviting to Islam) to women if there is someone more capable than them. As for those who believe themselves firm [against temptation], they may engage in da'wah with conditions: not speaking excessively outside the topic, refraining from joking or softening their voice, and not asking about personal matters. It is preferred that guidance be provided through female callers to Islam (da'iyat), or other da'wah methods, or by several individuals. Communication must cease if the heart begins to lean towards attachment or lust. As for the new Muslimah, the limits of the relationship and their wisdom are explained to her, and she is connected with Allah for her steadfastness. She should be treated gently if she violates the Sharia until Islam becomes firmly rooted in her heart.
