Аль-Араф 7:129

Then the prophet also explained why he was presenting a solution which was against the general way of thinking of the community; though these problems apparently stemmed from the ruling authority and were resolvable only by that ruling authority, the more important point for consideration was how power and authority came to be wielded. Nobody wields power simply as a result of strategies; power is bestowed or taken away directly by God. This being so, it follows that the solution to the problem also lies in God. Then, this power, regardless of whoever it is bestowed upon, is in fact a test for the recipient. In this world, being powerful is as much of a test as being powerless. Today, if one has received power, it is because he is being tested on whether he will become haughty and tyrannical, or will behave with justice and modesty. If empowerment is conferred upon others, even then the purpose will be to test others. If, due to its incompetence, one group has power taken away from it and handed over to another group, and if this other group also proves incompetent, power will likewise be taken away from it and given to yet another group. The prosperity and power for which a man pines in this world are in fact, assets that are attainable in the real sense only in the Hereafter: thus in the world these things are conferred on human beings solely to put them to the test, while in the Hereafter they will be given to the righteous people as rewards.
