(5) باب فَضِيلَةِ الإِمَامِ الْعَادِلِ وَعُقُوبَةِ الْجَائِرِ وَالْحَثِّ عَلَى الرِّفْقِ بِالرَّعِيَّةِ وَالنَّهْيِ عَنْ إِدْخَالِ الْمَشَقَّةِ عَلَيْهِمْ
It has been narrated on the authority of Hasan who said:
Ubaidullah b Ziyad visited Ma'qil b. Yasir al-Muzani in his last iliness. Ma'qil said (to him): I am narrating to you a tradition I heard from the Messenger of Allah (ﷺ). If I knew that I am to survive this illness. I would, not narrate it to you. I heard the Messenger of Allah (ﷺ) say: If God appointed anyone ruler over a people and he died while he was still treacherous to his people, God would forbid his entry into Paradise.
