Abu Najeeh reported,
I heard the Messenger of Allah ﷺ say, "Whoever lets fly an arrow in the cause of Allah, it will be a rank for him in Paradise." That day I let fly sixteen arrows.And I heard the Messenger of Allah ﷺ say, "Whoever shoots an arrow in the cause of Allah, it is equivalent to freeing a slave."
