It was narrated from Anas that the Prophet (ﷺ) used to deliver the sermon leaning on a tree trunk. When he started to use the pulpit, he went to the pulpit, and the trunk made a sorrowful sound. So he came to it and embraced it, and it calmed down. He said: “If I had not embraced it, it would have continued to grieve until the Day of Resurrection.”
