Sahih al-Bukhari
Virtues and Merits of the Prophet (pbuh) and his Companions
Chapter: The signs of Prophethood in Islam
Narrated Anas bin Malik:
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."
