Machine translationRead the Arabic original
Question:
If I buy a commodity from a person and want to sell it to another, but I cannot find anyone to buy it from me, is it permissible for me to sell it to the first person?
Answer:
If there is a prior agreement between you, it is not permissible. However, if there is no prior agreement and you sell it to him just as you would sell it to anyone else, there is nothing wrong with it.
