The Book on Government (Kitab Al-Imara)
Muslim :: Book 20 : Hadith 4714
It has been reported by 'Abd al-Rahman b. Shamasa that Fuqaim al- Lakhmi said to Uqba b. Amir: You frequent between these two targets and you are an old man, so you will be finding it very hard. 'Uqba said: But for a thing I heard from the Holy Prophet (may peace be upon him), I would not strain myself. Harith (one of the narrators in the chain of transmitters) said: I asked Ibn Shamasa: What was that? He said that he (the Holy Prophet) said: Who learnt archery and then gave it up is not from us. or he has been guilty of disobedience (to Allah's Apostle).
