When I made mention of that to the Prophet ( صلی اللہ علیہ وسلم ), he said, "Find them and get them back, and do not sell them except that they are together."

And I hope that when I meet Allah, the Most High, none of you will have any claim on me for an injustice regarding blood or property."

Muslim has: "He has three days in which to decide to keep them or not." Another narration by Muslim, which al-Bukhari reported as Mu'allaq (with a broken chain), has: "He must return with it one Sa' of any grain but wheat."

So, he asked, "What is this, O owner of the grain?" He replied, "Rain had fallen on it, O Allah's Messenger." He said, "Why did you not put it (the damp part) on the top of the foodstuff so that people might see it? Whoever cheats has nothing to do with me." [Reported by Muslim] .
