Furthermore many Muslims are using online chats to seek friends and chat, but as we all know most men and women are seeking more than just friends. They are possibly looking for a future wife or husband. You have raised a number of serious questions. First is the question about the Internet Chats between males and females. Third is the question about discussing private and intimate details of one's life with others.
Internet chat is very similar to writing letters or talking to someone on phone.
Actually it is a combination of both. Muslims have to observe the same rules as they observe in writing letters or making telephone calls. Islam does not permit love letters or intimate conversations between males and females who are not married to each other. In all our correspondence and conversations we must observe Haya or modesty. Boys and girls should not chat with each other just for socialization and to pass time.
