Booking a hotel room for someone who will use it for zina

Q: A person I know does online booking reservation for hotels and rooms for accommodation for 5 star hotels. Some of the clients that approach him are confirmed unmarried adults who want to book rooms for zina purposes. When it is 90% sure that these are unmarried and are booking for unlawful things, if I book the hotel rooms through my website, will it be halaal income or haraam income?

Using someone's credit card and paying back with extra

Q: I live with my parents, and over the past few months, I've made some online purchases using my father's credit card (with his permission). Since there have been quite a few transactions, I’d like to repay him but it would take a bit of time to track every individual purchase. 

Is it permissible if I give my father an amount that is more than the total of my purchases, ensuring I cover the minimum amount I owe him? 

For example, if the purchases total $1000, I would return something like $1200 to cover any uncertainty.

Selling an unclaimed collateral to retrieve one's money

Q: A year ago, I had a customer who wished to purchase an item for R1200. He only had R800. So he opted to leave his spare wheel with me. I told him that if you don’t come, I’m going to sell your spare wheel, he said yes, no problem, but I’m going to come. 

It’s been a year; I can’t get hold of him and he hasn’t come back. The spare wheel is worth about R2000. What should I do? Should I sell the spare wheel for R2000, take my R400 and give the remainder in Sadaqah, or should I sell it for R400?

Selling musical instruments

Q: I am in the business of selling sound equipment like speakers, mixers, and amplifiers. To remain competitive. I feel the need to offer a wider range of products, including musical instruments, despite knowing that music equipment may be considered haram. Given this, I have a few concerns: 

1. Is it permissible to sell musical instruments under these circumstances? 

2. If the income from selling such items is haraam, can I use that money to pay taxes? 

3. If selling musical instruments for profit is not permissible, would it be acceptable to sell them at cost price just to stay competitive in the market?
