Sunan Abi Dawud Book 15, Hadith 37
I heard the Messenger of Allah (ﷺ) say: Allah, Most High, will cause three persons to enter Paradise for one arrow: the maker when he has a good motive in making it, the one who shoots it, and the one who hands it; so shoot and ride, but your shooting is dearer to me than your riding. Everything with which a man amuses himself is vain except three (things): a man's training of his horse, his playing with his wife, and his shooting with his bow and arrow. If anyone abandons archery after becoming an adept through distaste for it, it is a blessing he has abandoned; or he said: for which he has been ungrateful.
AbuImran said: We went out on an expedition from Medina with the intention of (attacking) Constantinople. AbdurRahman ibn Khalid ibn al-Walid was the leader of the company. The Romans were just keeping their backs to the walls of the city. A man (suddenly) attacked the enemy.
Thereupon the people said: Stop! Stop! There is no god but Allah. He is putting himself into danger.
AbuAyyub said: This verse was revealed about us, the group of the Ansar (the Helpers). When Allah helped His Prophet (ﷺ) and gave Islam dominance, we said (i.e. thought): Come on! Let us stay in our property and improve it.
Thereupon Allah, the Exalted, revealed, "And spend of your substance in the cause of Allah, and make not your hands contribute to (your destruction)". To put oneself into danger means that we stay in our property and commit ourselves to its improvement, and abandon fighting (i.e. jihad).
AbuImran said: AbuAyyub continued to strive in the cause of Allah until he (died and) was buried in Constantinople.
‘Uqabah bin Amir Al Juhani said “I heard the Apostle of Allaah(ﷺ) recite when he was on the pulpit “Against them make ready your strength to the utmost of your power. Beware, strength is shooting, beware strength is shooting, beware strength is shooting.”
