It is narrated from Muhammad (al-Baqir), may Allah have mercy on him, that people who collected firewood came to the Messenger of Allah ﷺ and said: O Messenger of Allah! We are always on a journey, what should we do about the prayer? The Messenger of Allah ﷺ said: "Recite three tasbihs in the bowing (ruku‘) and three tasbihs in the prostration (sajdah)."
