Mukhtasar Bukhari

Narrated Jabir bin Abdullah (may Allah be pleased with him): There was a trunk of a date-palm tree which the Prophet (peace and blessings of Allah be upon him) used to stand by (while delivering the sermon). When a pulpit was placed for him, we heard a sound from that trunk like the crying of a pregnant she-camel for ten months, until the Prophet (peace and blessings of Allah be upon him) came down from the pulpit and placed his hand on the trunk. (Then the sound stopped.)
