Wa’il b. Hujr told that Salama b. Yazid al-Ju‘fi questioned God’s Messenger saying, “Prophet of God, tell us what you command us to do if commanders arise over us who demand of us what is due to them and refuse us what is due to us.” He replied, “Listen and obey, for they are responsible only for what has been laid on them (cf. Al-Qur’an, 24:54) and you for what has been laid on you.”
‘Abdallah b. Mas'ud told that God’s Messenger said to them, “After my death you will see appropriating the best things for themselves and other matters which you will disapprove.” He was asked what he commanded them to do and replied, “Give them what is due to them and ask God for what is due to you.”
‘Abdallah b. ‘Umar told that he heard God's Messenger say, “He who throws off obedience will meet God on the day of resurrection without possessing any plea, and he who dies without having taken an oath of allegiance will die like a pagan.”
Umm Salama reported God’s Messenger as saying, “You will have commanders some of whom you will approve and some of whom you will disapprove. He who expresses disapproval is guiltless and he who feels disapproval is safe, but he who is pleased and follows them ...” His hearers interrupted, “Shall we not fight with them?” but he replied, “No, as long as they pray; no, as long as they pray.” It means one who feels disapproval in his heart and expresses disapproval in his heart.
