Is it permissible for a young man and a young woman to communicate via the internet for the purpose of religious advice and sending religious materials, provided there is nothing between them that arouses suspicion?

It is not permissible for young men and women to converse online due to the sedition it causes, and Satan may beautify this under the pretext of da'wah (inviting to Islam). It is advisable to avoid such conversations to safeguard one's religion, and for women to continue da'wah exclusively among women. For the believing men and believing women are allies of one another; they enjoin what is right and forbid what is wrong.
