Arabic hadith text
وَعَنْ أَبِي سَعِيدٍ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّ إِبْرَاهِيمَ حَرَّمَ مَكَّةَ فَجَعَلَهَا حَرَامًا وَإِنِّي حَرَّمْتُ الْمَدِينَةَ حَرَامًا مَا بَيْنَ مَأْزِمَيْهَا أَنْ لَا يُهْرَاقَ فِيهَا دَمٌ وَلَا يُحْمَلَ فِيهَا سلاحٌ لقتالٍ وَلَا تُخبَطَ فِيهَا شجرةٌ إِلَّا لعلف» . رَوَاهُ مُسلم
Translation
Abu Sa'id reported the Prophet as saying, "Abraham declared Mecca sacred and made it a sacred area, and I declare Medina to be sacred throughout the area between its two mountain paths, so that no blood may be shed in it, weapons may not be carried in it for fighting, and leaves may not be beaten off trees in it except for fodder."Muslim transmitted it.
