Ma’qil Ibnu Yasar r.a. said that “I heard the Prophet (peace and blessings be upon him) as saying: Anyone among the slaves (of Allah) who was entrusted with the affairs of his subjects and he died in such a state that he was dishonest in his dealings with those over whom he ruled, Paradise would be forbidden for him.” (al-Bukhari 93:8, Muslim 1:6)
