Musnad Ahmad 944:32

'Abd al-Razzaq narrated to us, Sufyan informed us, my father narrated to me, from Ibrahim al-Taymi, from 'Amr ibn Maymun, from Abu 'Abd Allah al-Jadali, from Khuzaymah ibn Thabit, who said: "The Prophet, peace and blessings of Allah be upon him, set three days for the traveler, and a day and a night for the resident." And by Allah, had the questioner continued in his questioning, he would have made it five.
