‘Amr b. ‘Auf reported God’s messenger as saying, “The religion will shrink back to the Hijaz as a snake shrinks back to its hole, and the religion will seek refuge in the Hijaz as the mountain goat seeks refuge in the mountain top. The religion began few in number and will return to the state in which it began. Blessed are the few, for they will set right the corruptions caused in my sunna by people after my death.”
Tirmidhi transmitted it.
