Sayyiduna Khuzaymah bin Thabit (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) fixed three days for the traveller and one day for the resident. And by Allah, had the questioner persisted in his question, he (peace and blessings be upon him) would have made it five days.
