سنن أبي داود

Narrated Hamzat al-Aslami: I said: Messenger of Allah. I am a master of mounts and I use them ! I myself travel on them and I rent them. This month, that is, Ramadan, happend to come to me (while I am on a journey), and I find myself strong enough (to fast) as I am young, and I find that it is easier for me to fast than to postpone it, and i becomes debt due from me. Does it bring me more reward, Messenger of Allah, if I fast, or if I break ? He replied: Whichever you like, Hamzah.
