From Sahih Muslim (Hadith 4946):
It has been narrated on the authority of Ibn Amir who said:I heard the Messenger of Allah (ﷺ) say-and he was delivering a sermon from the pulpit: Prepare to meet them with as much strength as you can afford. Beware, strength consists in archery. Beware, strength consists in archery. Beware, strength consists in archery
