Sahih Muslim 1919

Muhammad ibn Rumh ibn al-Muhajir informed us: al-Layth informed us, from al-Harith ibn Yaqqub, from Abd al-Rahman ibn Shumasah, that Fuqaym al-Lakhmi said to Uqbah ibn Amir: “You keep going between these two targets, although you are an old man and it is hard on you.” Uqbah said: “Were it not for something I heard from the Messenger of Allah, I would not exert myself so.” Al-Harith said: I asked Ibn Shumasah, “What was that?” He said that Uqbah reported the Prophet saying: “Whoever learned archery and then gave it up is not one of us, or has disobeyed.”
