و در مقام ديگر * يا قوم لا تفسدوا في الارض و لا تسفکوا الدّماء و لا تأکلوا اموال النّاس بالباطل و لا تتّبعوا کلّ ناعق رجيم *
Translation
And yet again in another connection: "O people! Spread not disorder in the land, and shed not the blood of any one, and consume not the substance of others wrongfully, neither follow every accursed prattler."
