Hiring and Renting

Q: Is it permissible to lease one’s property to a conventional bank?

Q: I want to ask question about the personal work on job timings.

I have been working in a university as a software developer. During the job timing I'm working on my own work. Because the total university work that I got takes me only 2-3 days. The rest of the month I am free.

Can you please tell me the work that I have done during my job timing is haraam or halaal?

Q: I stayed with friends at a rented accomodation where in the agreement, only 2 people are allowed to stay each night for around 100$ per night. However, we lied to the owner and agreed that only 2 people will stay while actually 4 people stayed. We didnt think this was wrong since we would only use the accomodation for sleeping and wanted to save money. So technically we broke the agreement and cheated the owner.

What is the best way to fix this as we are afraid that in the akhirah, we will be punished, since we used his property not according to the agreement. If we reach out to him, he may take action against us so we are afraid. Could we pay him the money for the 2 extra people (we assume it will be 50$ per night per person) and give it to him anonymously? Or can we just donate this amount to chairty because we are afraid to tell him.

Q: I have a question regarding riba. I live in Germany and I want to rent a car for 12 months. My understanding is that all rental companies do not own the car, but they finance it from banks based on interest. As such, is it halal for me to rent cars?

Q: I read that it is impermissible to charge others to use a stallion as a stud. Does this mean that hiring out one’s stallion to impregnate someone else’s mare is impermissible? We breed and sell dogs for security purposes. Is it impermissible for one person to send his dog to get impregnated by someone else’s dog? One will have to pay for this.

Q: Is it permissible to enter into a fixed plan with ones energy supplier? By fixed plan I mean entering into a contract to pay a fixed price per kWh for any gas/electricity used during the coming year. The alternative is to remain on a variable plan, which means that the price of the gas/electricity fluctuates depending on market prices.

Q: We have given a portion of our house on rent. But mostly the tenants are hindu and perform prayers there. I want to know whether it would stop the angels from entering our portion and also whether it would affect barkat in any way?

Q: We have given a portion of our house on rent as it is very big and very difficult to clean and maintain. Our tenant, who is a Hindu, does his prayers according to his beliefs. I want to know whether it is permissible or not as the building is the same but the portion on rent is totally separate.

Q: A person has rented a new car on long term, three years. After three years the value of the car is evaluated. If you want you can buy the car. Is this type of transaction permissible?

Q: I currently live in a hostel. I talked to another hostel owner to book a room. He kept a room for me for over 4 days and he denied other people who wanted that room. Now in the morning, the current hostel warden showed me another room with fewer charges and I decided to stay in the current hostel and not to shift. Now, if I stay, did I go against my word (wada khilafi)? I am feeling extremely guilty and I am starting to worry about my beliefs because of the backing out. Can I just say sorry and give some fine?
