to a man who asked, 'Do you consider all these creatures as people?' said, 'Exclude from among them those who do not brush their teeth, sitting cross-legged in a narrow place, one who interferes in matters that do not concern him, debates about that which he has no knowledge, one who acts sick without an illness, one who falls apart without a calamity, one who opposes his friends in matters of truth that they have agreed upon, a proud person who is proud of his forefathers but he is devoid of their good deeds, so he is like a heath peeling off its bark bit by bit until it reaches its core, and he is like Allah's verse: They are like cattle; rather they are more astray.'
