On the Day of the Conquest of Mecca, Messenger of Allah ﷺ said, "Allah has made this town a sanctuary. Its thorny bushes should not be cut, its game should not be chased, and its fallen things should not be picked up except by one who would announce it publicly."
قَالَ رَسُولُ اللَّهِ ﷺ يَوْمَ فَتْحِ مَكَّةَ إِنَّ هَذَا الْبَلَدَ حَرَّمَهُ اللَّهُ لاَ يُعْضَدُ شَوْكُهُ وَلاَ يُنَفَّرُ صَيْدُهُ وَلاَ يَلْتَقِطُ لُقَطَتَهُ إِلاَّ مَنْ عَرَّفَهَا
