Urwah bin al-Zubayr (may Allah have mercy on him) narrated that Sayyiduna Iyad bin Ghanm and Sayyiduna Hisham bin Hakim bin Hizam (may Allah be pleased with them both) passed by the governor of Hims, who had made some Nabataean people stand in the sun. One of them said to the governor: O so-and-so! 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."
