Ruling on Lost Property in the Prophet’s Mosque

Question: Two years ago, I found a pen at the door of the Prophet’s Mosque. Do I have the right to keep this pen, or am I required to hand it over to the lost and found office in the mosque?

Answer: If it has value, give it to the lost and found office. If it is of little worth, like a worthless stick or a worthless sandal, there is no harm in taking it and using it. However, if it has value, announce it continuously; otherwise, hand it over to the lost and found office.
