It is narrated from Abu Hazim that he states he asked Sahl bin Sa’d (may Allah be pleased with him) what the pulpit of the Prophet ﷺ was made of. Sahl bin Sa’d (may Allah be pleased with him) replied: “Among the living, no one knows this better than I do. It was made from the wood of the tamarisk tree of Ghaba. The freed slave of such-and-such woman made it. And I saw the Messenger of Allah ﷺ when he sat on it, he faced the Qiblah, then said the takbir, then recited (Qur’an), then bowed (ruku’), then stepped down and prostrated (sajdah), then ascended the pulpit and recited, then bowed, then stepped down and prostrated.”
