Beware that for every blood (that is shed) there is an avenger and for every right there is a claimant. The avenger for our blood is like the judge for his own claim, and it is Allāh who is such that if one seeks Him, then He does not disappoint him, and one who runs away from Him cannot escape Him. I swear by Allāh, O Bani Umayyah, shortly you will see it (i.e. your possession) in the hands of others and in the house of your enemy. Know that the best looking eye is that whose sight catches virtue and know that the best hearing ear is that which hears good advice and accept it.
