Is it permissible to chat with girls online to arouse the husband, with the intention of ensuring he does not commit indecency with them?

Traveling to non-Muslim countries is fraught with dangers to one's religion, and it is difficult to maintain religious observances there. We advise the following:

1. Urge your husband not to remain in non-Muslim countries unless there is an extreme necessity. If he can take you with him, that would be good. 2. It is not permissible for a woman to speak with another woman in a manner that incites desires. 3. It is not permissible for a man to speak with a woman who is not his mahram (definition) without need. 4. Do not respond to your husband's invitation to chat with girls online, as there is no need for it. Make him understand that a committed Muslim woman is not permitted to engage in such matters. 5. Remove doubts from your heart and think well of a Muslim. Do not speak to him as if he were a stranger to test him, unless he openly commits immorality. 6. Guide and advise him through indirect means, such as mentioning distinguished Islamic websites. 7. Reduce your internet usage and be wary of harmful chat and dialogue websites.
