What is the ruling on selling complete goods imported from abroad at the market price?

The questioner : Okay, a second question, Shaykh. If I have money and I buy goods in my house, and I sell them to this man at the market price, but my stock of that item is not complete, so I buy some from outside to complete the order for him, is there anything haram (forbidden) in that?

The Shaykh : Unless it is made clear. Yes, if you bought it and the man made a special account for me and paid the owner of the business, that is lawful. But if he relies on you because you are a knowledgeable person, and you come and negotiate with him to take the same price that he would buy for if he went alone, which he would not be given.

The questioner : Peace.

The Shaykh : No, I did not buy it specifically for this person. It is available at your shop. So you sell it to him as he would buy it outside. Unless he also tells you, "You need to look after us, and you need to do this," then it is up to what you agree upon with him.

The questioner : Okay, it has become clear to you, our Shaykh.

The Shaykh : You did not return.

The questioner : The merchandise is complete.

The Shaykh : Did he not answer you? May Allah guide you. He answered you: unless it is made clear.

The questioner : Unless you clarify that my stock of this item is incomplete and I need to buy it from outside. If I buy it at, for example, the wholesale price, I want to sell it at the retail price.

The Shaykh : My brother, this is well known, except for the clarification.

The questioner : Except for the clarification. May Allah reward you with good.

The Shaykh : May Allah keep you safe.
