The Prophet ﷺ used to deliver his sermons leaning against a palm trunk. When a pulpit was made for him, he moved to it, and the trunk moaned in longing. So he came to it and stroked it with his hand.
كان النبي ﷺ يخطب إلى جذع، فلما اتخذ المنبر، تحول إليه، فحن الجذع، فأتاه فمسح يده عليه.
Bukhari related it in the Book of Virtues (3583), from Muhammad bin Muthanna, who said, Yahya bin Kathir Abu Ghassan narrated to us, who said, Abu Hafs, whose name was Umar bin Ala, brother of Abu Amr bin Ala, narrated to us, who said, I heard Nafi, from Ibn Umar, and he related it.
