I will be harsh and stern against the aggressor, but I will be a pillar of strength for the weak.
I will not calm down until I will put one cheek of a tyrant on the ground and the other under my feet, and for the poor and weak, I will put my cheek on the ground.
Remember, I have not appointed you as commanders and tyrants over the people. I have sent you as leaders instead, so that the people may follow your example. Give the Muslims their rights and do not beat them lest they become abused. Do not praise them unduly, lest they fall into the error of conceit. Do not keep your doors shut in their faces, lest the more powerful of them eat up the weaker ones. And do not behave as if you were superior to them, for that is tyranny over them.
As quoted in Omar the Great : The Second Caliph Of Islam (1962) by Muhammad Shibli Numani, Vol. 2, p. 33
Take account of yourselves before your are brought to account.
I know that you are a Black Stone, you do not cause benefit or harm; and if it were not that I had seen Allâh’s Messenger – peace and blessings of Allâh be upon him – kiss you, I would never have kissed you.
