[Machine] The Messenger of Allah ﷺ was asked about lost property, and he said, "It should be announced and not hidden or kept secret. If its owner comes, then it belongs to him. Otherwise, it is the property of Allah, and He gives it to whom He wills."
أَنَّ رَسُولَ اللهِ ﷺ سُئِلَ عَنِ اللُّقَطَةِ فَقَالَ «تُعَرَّفُ وَلَا تُغَيَّبُ وَلَا تُكْتَمْ فَإِنْ جَاءَ صَاحِبُهَا فَهُوَ لَهُ وَإِلَّا فَهُوَ مَالُ اللهِ يُؤْتِيهِ مَنْ يَشَاءُ»
