Missing Items and Picking Them Up.
Whoever finds something in a road or anywhere else, does not know its owner, and took it—s/he is obliged to keep it with him/her and treat it like a deposit. S/he is not to be guaranteed because of it, except only if s/he neglects or does wrong with it. One must announce it for one year in the place where he thinks that its owner might be—for example, a market, road, or anywhere similar. This is the case even if it was very cheap, as s/he does not know if its owner will forgive him/her or not. Whoever does not follow this shall be considered a violator. As the Prophet Muhammad, peace and blessings be upon him and his progeny, said: ((The missing thing that was missing from a believer will cause the one who takes it to be thrown to Hell)).
So if one lost hope in finding its owner after that year, that one may pay it to a needy person or in a charity, and he must not take it for himself.
