Narrated Ibn Abbas: The Prophet said, "Whoever disapproves of something done by his ruler then he should be patient, for whoever disobeys the ruler even a little (little = a span) will die as those who died in the Pre-lslamic Period of Ignorance. (i.e. as rebellious Sinners).
— Sahih Bukhari, Volume 9, Book 88: Afflictions and the End of the World, Hadith #176
