(85) باب فَضْلِ الْمَدِينَةِ وَدُعَاءِ النَّبِيِّ صلى الله عليه وسلم فِيهَا بِالْبَرَكَةِ وَبَيَانِ تَحْرِيمِها وَتَحْرِيمِ صَيْدِهَا وَشَجَرِهَا وَبَيَانِ حُدُودِ حَرَمِهَا
Jabir (Allah be pleased with him) reported Allah's Apostle (ﷺ) as saying:
Ibrahim declared Mecca as sacred; I declare Medina, that between the two mountains, as inviolable. No tree should be lopped and no game is to be molested.
