The ruling on one who finds a sum of money and its identification

Question:
The Shaykh’s case: A person found a sum of five thousand riyals and asked about it many times before, but he did not find its owner. What is the ruling on this amount? And if its owner is found, does he have any right to it? The customary practice is that the finder takes less than ten percent or one percent of the value of the amount. Is this correct?

Answer:
We have stopped at the section on lost property. However, one who finds lost property must identify its distinguishing marks, then call out for it in the markets and in the gathering places of people for a period of one year. He calls out for it in the gathering places of people and the markets for one year. If a year passes and no one comes forward despite the calling out, he owns it. It becomes his property. But if its owner comes in the future, he pays it to him. If the owner does not come, it is his property. This is the ruling on lost property. Yes.
