باب فَضْلِ الْحَرَمِ
Sahih al-Bukhari 1587

Narrated Ibn `Abbas:

On the Day of the Conquest of Mecca, Allah's Messenger (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."

حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ، حَدَّثَنَا جَرِيرُ بْنُ عَبْدِ الْحَمِيدِ، عَنْ مَنْصُورٍ، عَنْ مُجَاهِدٍ، عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ ـ رضى الله عنهما ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمَ فَتْحِ مَكَّةَ ‏ "‏ إِنَّ هَذَا الْبَلَدَ حَرَّمَهُ اللَّهُ، لاَ يُعْضَدُ شَوْكُهُ، وَلاَ يُنَفَّرُ صَيْدُهُ، وَلاَ يَلْتَقِطُ لُقَطَتَهُ إِلاَّ مَنْ عَرَّفَهَا ‏"‏‏.‏
