The Messenger of Allah ﷺ said on the morning of Aqaba, while he was standing on his mount, "Pick up some pebbles for me." So I gathered for him small pebbles, the size of pebbles used for flicking, and placed them in his hand. He began to move them about in his hand, and Yahya demonstrated how he shook them in his hand, saying, "With pebbles like these."
