He said, "Declare them publicly for one year." So I declared them publicly, but they were not claimed. So I returned, and he said, "Declare them publicly for one more year, declare them publicly for one more year." I did that two or three times, then the Messenger of Allah ﷺ said, "Determine its value, its container, and its cover, and mix it with your wealth. If its owner comes, give it to him."'
