The Prophet (ﷺ) 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 al-Bukhari Book 92, Hadith 6
← Previous Hadith Allah's Messenger (ﷺ) said to us, "You will see after me, selfishness (on the part of other people) and other matters that you will disapprove of." They asked, "What do you order us to do, O Allah's Messenger (ﷺ)? (under such circumstances)?" He said, "Pay their rights to them (to the rulers) and ask your right from Allah."

Sahih al-Bukhari Book 92, Hadith 5 Next Hadith → The Prophet (ﷺ) said, "Whoever notices something which he dislikes done by his ruler, then he should be patient, for whoever becomes separate from the company of the Muslims even for a span and then dies, he will die as those who died in the Pre-lslamic period of Ignorance (as rebellious sinners).
