767. It was narrated from Abu 'Abdullāh, the freed slave of Shaddād bin Hād that he heard Abu Hurairah say: "I heard the Messenger of Allāh ﷺ say: 'Whoever hears a man making a lost-and-found announcement in the mosque, let him say: "May Allāh not return it to you!" For the mosques were not built for that.'" (Sahih)
