Judgments (Ahkaam)

Bukhari :: Book 9 :: Volume 89 :: Hadith 257

Narrated Ibn 'Abbas:

The Prophet said, "If somebody sees his Muslim ruler doing something he disapproves of, he should be patient, for whoever becomes separate from the Muslim group even for a span and then dies, he will die as those who died in the Pre-lslamic period of ignorance (as rebellious sinners). (See Hadith No. 176 and 177)
