Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: "A time will soon come when the best wealth of a Muslim will be sheep, which he will take with him to the tops of mountains and places of rainfall, fleeing with his religion from tribulations."
