Musannaf Ibn Abi Shayba 33:1213

Haram ibn Hayyan was a governor over some of the districts of al-Ahwaz. A man from his companions asked his permission to go to his family, but he refused to give him permission. He said: Then Haram ibn Hayyan stood up to deliver the sermon on Friday, when the man did like this to his nose—he held his nose—so Haram signaled to him with his hand, "Go." The man departed until he reached his family and fulfilled his need, then he returned. Haram said to him, "Where were you?" He said, "Did you not see when I stood up and held my nose, and you signaled to me with your hand, 'Go'?" Haram said, "O Allah, delay the evil men for an evil time."
