That he heard Jabir bin `Abdullah saying, "The roof of the Mosque was built over trunks of datepalms
working as pillars. When the Prophet (ﷺ) delivered a sermon, he used to stand by one of those
trunks till the pulpit was made for him, and he used it instead. Then we heard the trunk sending a
sound like of a pregnant she-camel till the Prophet (ﷺ) came to it, and put his hand over it, then it became
quiet."
Sahih al-Bukhari Book 61, Hadith 94
