(30) باب ذِكْرِ مَا يَجِبُ لِلإِمَامِ وَمَا يَجِبُ عَلَيْهِ
Abu Hurairah narrated that the Messenger of Allah said:
"The Imam is like a shield whose orders should be obeyed when they (the Muslims) fight, and where they should seek protection. If he enjoins fear of Allah and behaves justly, then he will be rewarded, but if he enjoins otherwise, then it will be a burden (of sin) on him."
