Abu Umama reported the Prophet as saying, “No one will rule ten people or more without coming to God who is great and glorious on the day of resurrection with his hand chained to his neck and being set free by his goodness, or brought to destruction by his sin. The beginning of it merits blame, its middle produces regret, and its end is disgrace on the day of resurrection.”
Abu Dharr told that God’s Messenger said to him for six days, “Comprehend, Abu Dharr, what will be said to you afterwards.” Then when the seventh day came he said, “I counsel you to observe fear of God both secretly and openly; when you do wrong do a good deed; do not ask anyone for anything, even if your whip falls;* do not accept a trust; and do not give a decision between two people.”
Ahmad.
* This means that help is to be asked only from God and that one should not ask another human being for even the smallest help.
Mu'awiya reported God’s Messenger as saying, “If you are put in a position of authority, Mu'awiya, fear God and act justly.” He said that he kept thinking he would be afflicted by a governorship in accordance with what the Prophet had said till it actually came true.
Ahmad. Baihaqi transmitted Mu‘awiya’s tradition in Dalail an-nubuwa.
Narrated Jabir b. Samura told that he heard God’s Messenger say, “There are three things I fear for my people:
seeking rain by the stars,*the injustice of the ruler, and denial of God's decree.”
Ahmad.
*This is a reference to the pre-Islamic habit of attributing rain to certain seasons and saying the rain came to them because of a certain star, whereas Muslims ought to recognize that rain comes by God’s favour.
