This is prohibited as it is a loan that draws a benefit to the lender.

My friend is affiliated to “Company A” and he said me if i buy one product (which costs 250 dollars) from “company A” then he will give me a loan of another 250 dollars to buy another product. Is this transaction based on riba since i heard that there is a hadith which says it is haram to combine a sale and a loan..i want to know if my transaction is same like combining sale and loan?
