Business and Dealings

Q: I bought a brand new xiaomi smartphone in 2016. But the next year after I checked on government regulations website, my phone was "indeed" proven illegal. Illegal here means imported without any permissions from the government (not stolen, I already know the rules about stolen items). So no doubt about this. This leaves me questions:

1. What is the ruling for anything that we bought, we didn't know it is illegal at the beginning, but then it is proven illegal afterwards? (again, illegal here = "avoid taxes" not stolen items)

2. Am I allowed to continue using this or should I get rid of it?

3. What level of investigations should every Muslim do for each business transaction like this? 

Q: Is it permissible to sell cats?

Q: I am an engineer. I did manipulate my resume to get a job and I have experience in that job but I added no. of years experience in my resume because companies usually looks for no. of years experience. But I resigned from that company because I felt guilty and confused about haram or halal. On my previous company I did my work very well and I am a hard worker too. Is manipulating the resume is haram? If it is, then what about making money through that job and spending it for my family and my entire life? From last one year I don't have any job and i got no. of job offers with the previous resume and I rejected it. But this time I am so confused because in one place I saw it is fine if your giving 100 percentage to the company but there is no authentic sources. Now I got a offer letter and confused about it.

Q: My friend is planning to buy a petrol station. However, he requires R3 million and he only has R2 million with him. He asked me to help him by giving him R1 million so that the petrol station can be registered under his ownership. Thereafter, we will follow the conditions below:

Condition 1: He will give me full access to run the business for 3 years and all expenses and profits will accrue to me. He will have no share or involvement in the business for 3 years.

Condition 2: I have to give him a monthly rent (as per the current market in that location) for running the business on his property.

Condition 3: After 3 years, he will return the R1 million which I had given to him at the beginning. He says that this money will be considered as a security deposit and any damage or loss occurred during these 3 years will be deducted from it. Is this deal halaal or haraam?

Q: When making purchases, if there is a box to tick that says 'I have read and accept terms and conditions' But a person hasn't read them, is this sinful. Even if the purchase is something beneficial in Islam. (Note: Some terms and conditions can be pages and pages long like about 70 pages).
