The ruling on buying an item and selling it to a person whom one is likely to buy it from

Question:
The questioner, whose name is indicated by the letter Ayn, says: Is it permissible for me, Shaykh, to buy a commodity and then sell it to another person? I am certain and know that before I buy the commodity, he will buy it from me. Please note that there was no prior promise or agreement; rather, it is due to my knowledge of the person and my certainty that he will buy it from me.

Answer:
If you have concluded a contract and agreement with him that you will buy the commodity and sell it to him, then that is not permissible. However, if you buy it for yourself, take possession of it, and then sell it to him or to someone else, there is nothing wrong with that.
