What should a Christian woman who wishes to embrace Islam read or listen to in order to affirm her desire?

Friendship between a man and a woman is impermissible due to the corruption it engenders. However, this does not mean severing communication with a woman who wishes to embrace Islam. Such communication must adhere to the regulations of Sharia: there should be no private seclusion (khalwa) with her, nor looking at her awrah (parts of the body that must be covered). Conversation with her should be limited to what is necessary for inviting her to Islam. It is preferable that one of the Muslim sisters be entrusted with this task, based on the Prophet Muhammad's (peace be upon him) saying: "For Allah to guide a single man through you is better for you than having red camels."
