Ruling on the sale and purchase of stolen goods

Question:
A commodity was offered to me, and it became clear to me that it was stolen. However, the one who offered it to me was not the thief; rather, he had purchased it from another person who had bought it from the thief. If I buy it—knowing this—would I be sinful, even though I do not know the owner from whom it was stolen?

Answer:
What appears from the evidence of the Shari'ah is that it is not permissible for you to buy it if it becomes clear to you, or if you are strongly convinced, that it is stolen. This is based on the saying of Allah the Exalted: [Al-Ma'idah: 2]. Also, because you know, or are strongly convinced, that the seller is not its owner according to the Shari'ah, and has not been authorized by the Shari'ah to sell it. So how would you assist him in his injustice by taking the money of another without right?
Yes, if it is possible to buy it in order to rescue it and return it to its owner, there is no harm if it is not feasible to take it by force and punish the wrongdoer. However, if it is possible to take it by force and punish the wrongdoer with his prescribed punishment, then this is obligatory, based on the known evidence from the hadith: the hadith.
