Earning through giving good reviews on a website

Q: I need clarification on giving good paid reviews to a website. 

The previous week one individual from UK reached me on WhatsApp to start working on a website called intrepid travelling links. I worked about 3 hours giving reviews to the site. They pay us using bitcoin which we will convert to our local banks. I think the company pays for good reviews to boost their ratings. Is it halal? 

By giving reviews. Should I use it. Continue work or leave it. Reviews are given after using company services but they do this way. Should I use it regularly. Or I should work and spend the money on needy people? Kindly share as per Shariah.

Using company funds for hotel and expenses

Q: I have to visit KSA to conduct a workshop with customers and vendors. Customers and vendors requested to do workshops on weekends so we can save time and go to Umrah within this time line and requested to pay the same amount that will be saved by reducing the time of workshops and hotel accommodations so that we can manage our expenses for Umrah. 

I requested the company for this favor, and the company approved it for the vendor and customer, but when asked for myself, they replied, "we will book a hotel for as per your request and grade limit." When I checked with the relevant person, he told me your limit is 300 AED for a single night. You can book by yourself by booking online and share the booking receipt, and we will pay you. I have calculated that amount and now want to go with another hotel that has a lower rate, some 150 AED, and the rest amount will be used for travel and food during Umrah. Maybe some money can be saved by this. 

Can you please guide me? Is this halal or haram?

Returning money one had stolen and items one forgot to return

Q: 

1. How do I return money to someone I stole from. I've made taubah over many years and it's not a big amount (under R600) but I'm embarrassed to tell this person as it's a scholar and it may cause this person to distrust me (and I'm not untrustworthy as it was a genuine mistake that I've truly atoned for) and cause disgrace on my family (who are scholars). How can I return it without him knowing I stole it because I don't even live in the same city anymore and I'd have to give the money to a family member who still resides in his city? Is it possible for me to give out the money in charity on his behalf with no expectation of reward and solely give it in his name? 

2. Also with regards to having old textbooks from over 20 years ago from primary school, I forgot to return and a T-square from high school my principal borrowed me which I forgot to return all those years. How can I make up for that amaanah?

Selling customized products made on order

Q: If a person does not own any products, he cannot sell them according to the hadith. But what will be the ruling for customized products which are made on order? 

For example, furniture, customized packagings, custom business cards, custom printed clothes and many other things which are made only on order. These things cannot be kept in stock, because every product is made as per customer's requirements. Such products are neither with the seller nor with any factory. Because such products can be made only when the customer places the order, as per customer's requirements. 

So my question is whether I can take the order from the customer as per my price and give it to the factory? And can I take the full money from the customer in advance? Please clear my doubt.

Woman working due to living with an abusive mother

Q: I live with my mother who is mentally and physically abusive to me and my siblings. Last year, she broke my nose, she has called me ugly and stupid and worthless my whole life. She pushes me to do things that are detrimental to my mental health - like marrying someone 11 years older or getting into med school. 

I want to leave my household and make a life for myself so that I don’t constantly feel suicidal and can do some good in this world. But in order to leave, I must apply to programs that I do not have the qualifications for - there is a program that requires me to have one year work experience and I only have 6 months. 

Even though I do not want to lie, I was wondering if it might be permissible for me to do so in this situation just to help my chances of getting out my house?

Online trading

Q: Regarding online trading, be it a commodity or currency, it is been said that it's not permissible based on both exchanges being deferred and if 1 exchange is deferred and the other is not then is it permissible? 

Can you explain further what is meant by deferred exchanges?
