Musnad Ahmad 3407

It was narrated from Ibn 'Abbas (رضي الله عنه) that The Prophet (ﷺ) used to deliver khutbahs leaning on a palm trunk. When the minbar was made and he moved to it, the trunk groaned. The Messenger of Allah (ﷺ) went to it and embraced it, and it fell silent. He said: "If I did not embrace it, it would have groaned until the Day of Resurrection.”
