Jabir said that God’s messenger went off to Mecca in Ramadan in the year of the Conquest, and he and the people fasted till he came to Kura' al-Ghamim.* He then called for a cup of water which he raised till the people looked at it, and then he drank. He was told afterwards that some of the people had continued to fast, and said, “Those are the disobedient ones; those are the disobedient ones.”
*A wadi two stages from Mecca on the way to Medina.
Salama b. al-Muhabbiq reported God’s messenger as saying, “If anyone has a riding-beast which carries him to where he can get sufficient food he should observe the fast of Ramadan wherever he is when it comes.”
‘Abd ar-Rahman b. ‘Auf reported God’s messenger as saying, “One who fasts in Ramadan while travelling is like one who breaks his fast when not travelling.”
Anas b. Malik al-Ka‘bi reported God’s messenger as saying, “God has remitted half the prayer to the traveller, and fasting to the traveller, the woman who is suckling an infant and the woman who is pregnant.”
Abu Dawud, Tirmidhi, Nasa’i and Ibn Majah transmitted it.
