What did Prophet Muhammad (saw) say about rulers who do not make efforts for the welfare of the Muslims?
 It is narrated on the authority of Abu Malih that Ubaidullah b. Ziyad visited Ma'qil b. Yasar in his illness. Ma'qil said to him:                      I am narrating to you a hadith which I would have never narrated to you had I not been in death-bed. I heard Allah's apostle (may peace be upon him) say: A ruler who has been entrusted with the affairs of the Muslims but he makes no endeavors ( for the material and moral uplift) and does not sincerely mean (their welfare) would not enter Paradise along with them.
