I went on an expedition with the Prophet, and I was present with him at the Conquest. He stayed eighteen days in Mecca and prayed only two rak'as . He said, “You who live in the town must pray four; we are travellers.”
Ibn ‘Umar said, “When travelling I prayed along with the Prophet two rak'as at the noon prayer and two after it.” In a version he said, “I prayed with the Prophet both when resident and when travelling. When resident I prayed along with him four rak'as at the noon prayer and two after it, and when travelling two at it and two after it; two rak'as at the afternoon prayer after which he prayed no more; and both when resident and travelling alike three rak'as at the sunset prayer, in which he never prayed less whether resident or travelling, this being the witr of the daytime. After it he prayed two rak'as.”
Ibn ‘Umar said that on a journey God’s Messenger would pray on his riding beast in whatever direction it turned, making a sign with his head* in prayer during the night, but not in the obligatory prayers; and he would observe a witr on his riding beast.
