Chapter 96: Holding Fast to the Qur'an and Sunnah
Narrated 'Asim: I said to Anas, "Did Allah' s Messenger (ﷺ) make Medina a sanctuary?" He replied, "Yes, (Medina is a
sanctuary from such-and-such place to such-and-such place. It is forbidden to cut its trees, and
whoever innovates an heresy in it or commits a sin therein, will incur the curse of Allah, the angels,
and all the people." Then Musa bin Anas told me that Anas added, "..... or gives refuge to such an
heretic or a sinner..."
