Musannaf Ibn Abi Shaybah 22998 — Lost property: what is to be done

It is narrated from Abu al-Safar (may Allah have mercy on him) that a man from Banu Ru'as said: I found three hundred dirhams. I had them announced only slightly, and at that time I was needy myself. After the announcement, when I found no one, I consumed them. Later I became well off, so I asked Sayyiduna Ali (may Allah be pleased with him) about this. He (may Allah be pleased with him) said: Announce them for one year. If the owner comes, hand them over to him; otherwise, give them in charity on his behalf, and he has the choice either to take its reward (of the charity), or you make good his loss.
