Hasan says that when you go to the market, you may buy whatever you find, as long as you do not know that the item is stolen or embezzled (in that case, you should not buy it).

The Prophet Muhammad (peace be upon him) said: Whoever knows that something is stolen property and still buys it, then he is a partner in its theft and sin.

23470 - Abu Bakr narrated to us, he said: Waki‘ narrated to us from al-Rabi‘ from Ibn Sirin who said: I said to ‘Ubaidah: May I buy stolen goods while I know they are stolen? He said: No. I said: May I buy what is acquired through betrayal, while I know it is betrayal? He said: No. I said: May I buy what is gained from labor (2)? He said: And can you avoid it?

It is narrated from Hazrat Ubaidah in the same manner.
