‘Abdur-Rahman bin Sa’d bin ‘Ammar bin Sa’d narrated that his father told him, from his father, from his grandfather, that when the Messenger of Allah ﷺ delivered a speech on the battlefield he would do so leaning on a bow, and when he delivered a sermon on Friday, he would do so leaning on his staff.
أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا خَطَبَ فِي الْحَرْبِ خَطَبَ عَلَى قَوْسٍ وَإِذَا خَطَبَ فِي الْجُمُعَةِ خَطَبَ عَلَى عَصًا
