There will be tribulations during which the one sitting would be better than the one standing, and the one standing would be better than the one walking, and the one walking would be better than the one running. Whoever exposes himself to them [tribulations], they will overcome him. So whoever finds a refuge or a shelter from them should seek protection there.

It is soon that the best wealth of a Muslim will be sheep, which he follows to the peaks of the mountains and the places where rain falls, fleeing with his religion from tribulations.
