Disposing of lost items whose owners have not come forward

The questioner:
We work in large schools, and sometimes items belonging to others come to us.

The Shaykh:
What do we do?

The questioner:
We work in one of the large schools, and sometimes lost items come to us, specifically lost items,

The Shaykh:
Lost items, meaning things that are lost. Yes, that is correct.

The questioner:
Such as watches, jewelry, and things like that. Even if we announce these items repeatedly on the morning broadcast and no one comes to claim them, and they may remain for a year, a full year, is it permissible to dispose of these items by using them for zakah expenses or for some of the students or teachers?

The Shaykh:
They are given to the poor. They are given to poor students if you have done what is required and announced them, and no one has come for them, then you give them to the poor. Either you sell them, take the price, and give it in charity to the poor, or if there are poor people in need of them, you give them to those people. Yes.
