Now a day people use the Facebook and they chat with girls and boys. Is it Islamically right to chat with the members of opposite sex? Sometimes chatters make a good friend and share their knowledge of Islam. Would such interaction with the unrelated male and female individuals allowable?
If a non-Muslim living in full by means of usury business invites me for food in his house, can I go and eat his food? If yes, then may I know the proofs that conclude such results?
