Working in a company where the credit price is more than cash price

Q: I want to work in an electronics company that provides products on loan (12 months installments) And they take more money than the actual prize of the product. For example a product which costs 45,000 PKR (Cash) they give it at a total amount of 54,000 PKR (in installments). Can I work there? Will my earnings will be Halal?

Greeting a non-Muslim helper

Q: My nani is bedridden. She has a female Christian attendant who comes everyday in the morning and leaves at night. She wanted to know if she can say salam to her when she comes in the morning. If not, then how should she greet her when she comes? Not saying anything appears rude and cold.

• Creating and updating files

Disposing hair

Q: If a person shaves his moustache over the bathroom sink every morning, would this be OK even though the stubbles of hair will go down the drain? Or does he have to shave over a container to collect the stubbles of hair in order to bury them?
