question #1 Sahih al-Bukhari 633, Book 10, Hadith 30 : What is the significance of using a spear or stick during the prayer in Islamic tradition?

My father said, “I saw Allah’s Messenger (ﷺ) at a place called Al-Abtah. Bilal came and informed him about
the prayer and then came out with a short spear (or stick) and planted it in front of Allah’s Messenger (ﷺ) at
Al-Abtah and pronounced the Iqama.”
