Sayyiduna Hisham bin Hakim (may Allah be pleased with him) saw that Iyad bin Ghanm (may Allah be pleased with him), who was the governor of Hims, had made some Nabataean people stand in the sun in connection with the payment of the jizyah. So Hisham bin Hakim (may Allah be pleased with him) said: O Iyad! What is this? I heard the Messenger of Allah (peace and blessings be upon him) say: "Allah Almighty will torment those who torment people in this world."
