"Don't make yourself a yardstick for the truth. Rather, make the truth your yardstick. As for you saying: 'This is the truth because I'm saying this and doing this', you are not a yardstick for the truth. And don't make the men a yardstick for the truth, rather, make the truth a yardstick for knowing its people. Know the truth and you will be from its people. Know the truth and you will know its people."
Translated by Abu Yusuf Khaleefah
