Q: When people in my family get married, they normally make a big thing with the groom. They splash him and throw food on him and make a big noise. This is before the nikaah. When he gets married then they trouble the couple and on the first night they peep and other things.

Q: Wouldn't it be permissible for a husband to check his wife's phone and her messages in WhatsApp and social media?
