Malik related to me from Abd ar-Rahman ibn Abd ar-Rahman ibn
Sasaca from his father that Abu Said al-Khudri said that the Messenger
of Allah, may Allah bless him and grant him peace, said, "It will soon
happen that the best property of a muslim will be sheep which he takes
to the peaks of the mountains and the valleys, fleeing with his deen
from trials."
Muwatta Malik Book 54, Hadith 16
