← Previous Hadith "I heard the Messenger of Allah(s.a.w) while a man was asking him: 'What do you see that we should do if there are leaders over us who deny our rights, while they seek their rights?' So the Messenger of Allah(s.a.w) said: 'Listen and obey, for only they are responsible for their burdens, and only you are responsible for your burdens."'
