Is it valid to leave a lost item of value and not take it?

Question:
May Allah reward you. This questioner says: A person found an amount of three thousand riyals on the ground and did not take it. Is his action correct?

Answer:
Or appropriate? He should leave it. If he takes it and identifies its owner, if possible, since it has no distinguishing marks, because they are just papers, right? It is not tied up, nor in a container, nor with anything that has a distinguishing mark. So he should search for its owner. If he does not find him, he gives it in charity, intending the reward for its owner.
