Trials and Fierce Battles (Kitab Al-Fitan Wa Al-Malahim)
Dawud :: Book 35 : Hadith 4249
Narrated AbuMusa al-Ash'ari:
The Prophet (peace_be_upon_him) said: Before you there will be commotions like pieces of a dark night in which a man will be a believer in the morning and an infidel in the evening. He who sits during them will be better than he who gets up, and he who gets up during them is better than he who walks, and he who walks during them is better than he who runs. They (the people) said: What do you order us to do? He replied: Keep to your houses.
