Credit cards

Q: My question is that I live in muscat and I am a teacher. I want to start a side business. So the bank is offering me a credit card and the offer is that if I pay the money back I use from credit card in 52 days then no interest will be charged.

Sales rep taking a percentage of the profits

Q: Is it permissible to pay somebody for bringing in business? I work in sales and people (3rd party) bring me business. If I make a sale they ask me to give them money which is already decided it doesn't matter how much money I make on this sale, they want what ever is decided before. Now the question is if I pay somebody to bring me business then what about other guys who work with me in sales? Because if the (3rd party) doesn't bring it to me it will probably go to my coworkers please tell me what Islam says about it?

Laser hair removal

Q: Is it allowed in Islam to use a laser machine at home to remove your pubic hair? I ask this question because elders have told me it is not allowed in Islam because at the time of your janaazah your body becomes very very heavy and your soul does not leave your body if you use an object to remove your pubic hair. This is why I wanted to confirm whether it is or not allowed in Islam. I was intending to buy the lumea precision plus.

Marital Problems

Q: I am married and pregnant. I loved my husband so much and I am his second wife but his first wife is a problem to me because she is sending me messages all the time, but she is a Haafidha. But all that she says doesn't look like she has the holy Quran in her head and because of this I am tired of this man and I feel like separating from him. What should I do?
