"When the Messenger of Allah (ﷺ) delivered the khutbah, he used to lean against a palm tree trunk that formed one of the pillars of the masjid. When the minbar was made and he sat down on it, that pillar made a sound like the groaning of a camel, which the people of the masjid heard, until the Messenger of Allah (ﷺ) came down and embraced it, then it fell silent."
