Abu Huraira (Allah be pleased with him) reported:If I were to see deer grazing in Medina, I would have never molested them, for Allah's Messenger (ﷺ) has stated: There is between the two lava mountains a sacred territory
قَالَ حَرَّمَ رَسُولُ اللَّهِ صلى الله عليه وسلم مَا بَيْنَ لاَبَتَىِ الْمَدِينَةِ. قَالَ أَبُو هُرَيْرَةَ فَلَوْ وَجَدْتُ الظِّبَاءَ مَا بَيْنَ لاَبَتَيْهَا مَا ذَعَرْتُهَا. وَجَعَلَ اثْنَىْ عَشَرَ مِيلاً حَوْلَ الْمَدِينَةِ حِمًى.
Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (ﷺ) declared sacred the territory between two lava mountains of Medina. Abu Huraira said:If I were to find deer in the territory between the two mountains, I would not molest them, and he (the Holy Prophet) declared twelve miles of suburb around Medina as a prohibited pasture
