Musnad Abu Ya'la al-Mawsili 42:94

Masruq ibn al-Marzuban narrated to us, Yahya ibn Zakariya narrated to us, from Mujalid, from Abu al-Wadak, from Abu Sa’id, who said: The Prophet, peace and blessings of Allah be upon him, used to stand by a piece of wood, leaning upon it, to deliver the sermon every Friday. Then a man from the people came to him and said, "If you wish, I will make something for you so that when you sit upon it, you will be as if you are standing." He said, "Yes." He said: So he made the pulpit for him. When he sat upon it, the piece of wood moaned like the moaning of a she-camel for her young, until the Prophet, peace and blessings of Allah be upon him, descended and placed his hand upon it. When the next day came, I saw that it had been moved. We said, "What is this?" They said, "The Prophet, peace and blessings of Allah be upon him, came last night, along with Abu Bakr and Umar, and they moved it."
