friendship

Respected scholars, as-salamu `alaykum. I have tried to convince my husband that it is haram to speak with the other women for social and friendship purposes, although they are university colleagues. However, he doesn't seem to realize the importance of this issue and the problems it causes between us. I trust that there is no bad intention in his mind, but it still bothers me. What can I do to help him and myself? Jazakum Allahu khayran.

It's very common nowadays to have friends from the opposite sex and many would kiss and hug for greeting. The general belief is that these are only innocent friendships and that the feeling is the same as that between brothers and sisters. Could you please clarify the ruling in Islam on:a)making friends between the opposite sexes. b)hugging and kissing the opposite sex with no lust Kindly provide evidence.
