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.

As quoted in Al Farooq, Umar (1944) by Muhammad Husayn Haykal, Ch. 5, p. 124
