Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Trials will overwhelm you like pieces of the dark night. In (the era of) those trials, the safest of people will be a man who lives on a mountain peak and subsists on the milk of his goats, or a man who holds the reins of his horse beyond the frontiers and eats from the earnings of his sword." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs did not record it.
