Musannaf Ibn Abi Shaybah 22995 — Lost property: what is to be done

It is narrated from Amr bin Shu'ayb, from his father, from his grandfather, who said: I heard a man from Muzaynah asking the Prophet (peace and blessings be upon him): What should we do with a lost item that we find on an inhabited road (where people come and go in large numbers)? He (peace and blessings be upon him) said: Announce it for one year. If its owner is found, well and good; if not, then it is yours.
