Sayyiduna Karz Khuzai (may Allah be pleased with him) narrates: A Bedouin said: O Messenger of Allah (peace and blessings be upon him)! Will there be any end to this Islam? The Prophet (peace and blessings be upon him) said: Yes, Allah Almighty will admit into Islam whomever He wills from among the Arabs and non-Arabs. The Bedouin said: O Messenger of Allah (peace and blessings be upon him), then what will happen? The Prophet (peace and blessings be upon him) said: Then there will come tribulations like darkness. That person said: Never, by Allah! O Messenger of Allah (peace and blessings be upon him)! (This will not happen). The Prophet (peace and blessings be upon him) said: Yes, by Him in Whose hand is my soul (it will happen), and you will again fall into such a situation that you will spread your hoods like snakes and begin to strike off each other's necks. In that time, the best person will be the believer who lives alone in a mountain pass, fears Allah Almighty, and keeps people safe from his own evil.
