question #3 Sahih al-Bukhari 7057, Book 92, Hadith 9 : What guidance does Islam provide for maintaining one’s duties towards leaders despite personal grievances?

A man came to the Prophet (ﷺ) and said, “O Allah’s Messenger (ﷺ)! You appointed such-and-such person and
you did not appoint me?” The Prophet (ﷺ) said, “After me you will see rulers not giving you your right
(but you should give them their right) and be patient till you meet me.”
