Ruling on making up small amounts of money for unknown people

This is a message we received from Iraq. Its sender, Ahmad Abdullah Hamad al-Shalal from the Ninawa Governorate, district... and so on, says: In the year 1974, I performed Hajj at the Sacred House of Allah. When the period of Hajj ended, we traveled to our relatives. When we left Kuwait for Iraq, we pilgrims donated to the driver of the car that brought us to the Sacred House of Allah, with each pilgrim contributing two dinars. I collected the money, and some money remained for some of the pilgrims with me, one or two riyals for each person. We were many, about forty pilgrims, and those who had money left with me were about ten pilgrims. When we arrived in Iraq, they scattered and I did not know their houses. Please inform us, may Allah reward you for us, what should I do with this money?
Answer: This money is small and easy, and it is in the category of what is excused. If you eat it, there is no harm, and if you give it in charity, there is no harm, as long as it is one or two riyals, its matter is light. The rule is that a small amount of lost property is permitted for the finder to take, and there is no blame on him for that. If you give it in charity on their behalf and give it to some of the poor, that is good, and there is no blame on you for eating it or giving it in charity. Yes.
