Anger of Rasoolullah (Sallallahu alaihi wasallam)

When the Haq was trampled upon then the anger of Rasoolullah (Sallallahu alaihi wasallam) was unstoppable until he restored the Haq to its position of dominance. He would, however, neither become angry out of self-interest and nor would he avenge on account of a personal matter. (Nashrut Teeb)
