Selling an item to a person who requires a loan

Q: One of my colleagues asked me to lend him some money like 10 thousand which he wanted to use for his personal use. He said he would give me back 12 thousand in one month. I rejected his offer saying it is haraam. He asked me to buy him something like a computer for 10 thousand and he was ready to buy it from me at 12 thousand. But he would give me after 1 month. If he pays early, no discount and if he pays late, no extra money he will give but I can demand my money after 1 month. He purchased from me and he sold it in the market and got cash to satisfy his needs. Later after one month he gave me 12 thousand. Is the profit of 2 thousand haraam?

Gifts from customers

Q: Please advise on the permissibility of the following two gifts:

1. I recently went to Asia on a business trip on behalf of the company for which I work. I visited numerous Asian customers who gave me a small gift. I assume that this is part of the Asian culture.

2. One of the sales managers who gives out year-end gifts to our customers, gave me one of these gifts. I believe that this was surplus stock. Please advise in each case whether it is permissible to keep these gifts.
