An Arabi came to the Messenger of Allah ﷺ and asked, "By what means can I know that you are a prophet?"He replied, "If I call this cluster of dates from this palm tree, will you testify that I am the Messenger of Allah?"So the Messenger of Allah ﷺ called it, and it began descending from the palm tree until it dropped down before the Prophet ﷺ.
