My questions is as follows:

وَفِي الشَّرِيعَةِ: الرِّبَا: هُوَ الْفَضْلُ الْخَالِي عَنْ الْعِوَضِ الْمَشْرُوطِ فِي الْبَيْعِ؛ المبسوط للسرخسي

How will you explain this definition of riba in relation to the mas’alah in question? 

I have three objections: 

1. The extra amount is not necessarily خاليًا عن العوض (free of consideration). There is a service or benefit being provided in return for the amount charged. So how can this extra amount be described as a “surplus without consideration”? 

2. The extra amount is not مشروطًا في العقد (stipulated in the contract). The definition specifically refers to an excess that is stipulated in the sale. If this extra amount was not stipulated as a condition in the original contract, then how does it fall under this definition of riba? 

3. More importantly, how would it even be possible to pay the bank transaction fees in the first place? According to the qiyās presented in the mas’alah, paying the bank a fee gives them an additional benefit. If every additional benefit received by the lender is treated as riba on this basis, then what would be the basis for allowing bank transaction fees?

Q: Is it permissible in Islam to take a student scholarship from a riba based bank? 

The father is a guard man and the mother is a cook. 

Q: My friend asked me for a loan of R10 000. He said that he will pay me back the R10 000 after a week. There is no extra amount that I asked him to pay over and above the R10 000. However, since he asked me to eft the amount to him through which my bank will charge me R7, I asked him to pay my bank charges i.e. to pay the R7 which my bank will be charging me to do the eft. Is it permissible for me to take the R7 from him for the eft charge?

Q: My friend asked me for a loan of R100 000. He asked me to bring the money to him. I live in Pmb and he lives in Durban. Is it permissible for me to ask him to pay my petrol money for me to bring the R100 000 to him (i.e. R200)?

Q: If I have a choice on whether my bank account will earn interest or not which is better to choose? If I earn the interest I will donate it to the poor and someone will benefit. If I don’t take the interest the bank will benefit.

Q: I host tournaments on a game called Fortnite. People pay me a fee. Everyone to take part in these tournaments, and I pick a few of them every weekend to take part in the tournament. I give the top 3 prizes and sometimes cash rewards, prizes like perfumes, clothes etc. 

Is this what I am doing halaal earned money, I make profit of this too.
