حَدَّثَنَا إِبْرَاهِيمُ، عَنْ مُسْلِمٍ، حَدَّثَنِي زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا شَبَابَةُ، حَدَّثَنِي وَرْقَاءُ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّمَا الإِمَامُ جُنَّةٌ يُقَاتَلُ مِنْ وَرَائِهِ وَيُتَّقَى بِهِ فَإِنْ أَمَرَ بِتَقْوَى اللَّهِ عَزَّ وَجَلَّ وَعَدَلَ كَانَ لَهُ بِذَلِكَ أَجْرٌ وَإِنْ يَأْمُرْ بِغَيْرِهِ كَانَ عَلَيْهِ مِنْهُ " .
English Translation
It has been narrated on the authority of Abu Huraira that the Prophet of Allah (ﷺ) said:A commander (of the Muslims) is a shield for them. They fight behind him and they are protected by (him from tyrants and aggressors). If he enjoins fear of God, the Exalted and Glorious, and dispenses justice, there will be a (great) reward for him; and if he enjoins otherwise, it redounds on him
