Lost and Stolen items

Selling a stolen phone

Q: I bought a phone to sell from someone but when they came to sell it while I'm paying them they say the phone is on contract and they have a way of wiping the name of the person who took the contract off from the database etc. so they don't have to pay etc.

Afterwards I realized it's like stolen so I messaged the person and told him I want to return it but he's now insisting that the contract will be paid for monthly.

What do I do? I sold the phone now, what do I do with the money from it? Is it halal for me to use or must give it away in charity?

Returning an item that does not belong to you

Q: When I was a child I remember one of the neighbours close to us had a garden that from what I remember was quite messy like things were about and one thing there was a tricycle and it looked like the one I had when I was a child and to think at the time I thought someone must have dumped my tricycle there so I took it out.

However I cannot ascertain if it did belong to me and perhaps I took someone’s tricycle, maybe I thought the garden was messy so my tricycle was dumped there.

I believe the family have moved out now and there are new owners of the house. Would I have to approach the current owners to see if they are in contact with the old owners so I can ask the old owners for forgiveness and pay them if that is required of me.

Forgiving someone for stealing money

Q: I'm an 18 year old female and I used to buy lots of personal stuff, for example, an expensive keyboard and mouse, a pair of headphones etc. but I bought these items using the money I stole from my father's wallet without his knowledge and might have stolen some from my mother's purse too. I felt guilty about my deeds later on and I stopped stealing like that and I also told my dad that I stole his money to buy things for myself. He understood the topic and he said he forgave me.

Now first of all, are all the things that I bought using my dads stolen money haraam for me to touch or use ? Even after he forgave me? Do I stop using these stuff? Some of the stuff are actually important for me to use. Do I have to return these goods to my parents? I bought makeup using the stolen money. Do I have to return that to my dad or do I have to pay him the amount that I stole? I estimated it around 600 USD (I didnt steal it in a day of course. It came up to that number day by day). I dont even have a job that I can earn that money and pay him back.

Secondly, the items are (as far as I remember) - a keyboard, a mouse and mouse pad, headphones for gaming, TONS of makeup (like alot), some dresses and accessories, ingredients for making D-I-Y lip balms (like oils and beeswaxes etc.) and empty tin and plastic containers (a LOT of these containers). Do I throw all these items away? Even after I've asked for forgivenesss from my mum and dad?

Thirdly, I also bought some gifts and stationaries with the stolen money from my parents. and the people whom I gave the gifts to, does the items become haraam for them to use and are they unintentionally committing sin because of me? 

Returning stolen money

Q: When I was younger, I was involved in petty crime (theft). Now that I am older, I realise my wrongdoing, and want to know how can I repay this debt.

1. I often took money from my late-parents, without their knowledge. Now that they have passed away, how do I repay this debt?

2. I often took money from my late grandparents, without their knowledge. Now that they have passed away, how do I repay this debt?

3. I often took money from friends, without their knowledge. They are still alive, how do I repay this debt? Do I need to inform them of my transgression?

4. If I took R100, 20 years ago, what amount is due today? Is it the same amount or is there a calculation that I need to perform to allow for inflation?
