Imam Ali (as): The people have to have a ruler over them, be he pious or wicked, under whose rule the believer toils and the wicked seeks to make merry, and in which Allah decrees the final outcome, and under which the booty is collected, the enemy is fought, the roads are made safe, and the weak is protected from the powerful, until the pious rests and the wicked is cast aside.
