Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) and Sayyiduna Anas (may Allah be pleased with him) narrate that the Messenger of Allah (peace and blessings be upon him) used to deliver sermons while leaning against a trunk. When he arranged for a pulpit, that trunk began to weep. The Noble Prophet (peace and blessings be upon him) came to it and embraced it, and then it became silent. The Noble Prophet (peace and blessings be upon him) said: "If I had not embraced it, it would have continued to weep until the Day of Resurrection."
