Sunan Abi Dawud Book 4, Hadith 24
We went out on a journey along with the Messenger of Allah (ﷺ). He led us in the night prayer and he recited in one of the rak'ahs: "By the fig and the olive."
The Prophet (ﷺ) was engaged in the Battle of Tabuk. If he moved off before the sun had declined, he would delay the noon prayer till he would combine it with the afternoon prayer and would offer them together. If he moved off after the sun had declined, he would combine the noon and afternoon prayers, and then he proceeded; if he moved off before the evening prayer, he would delay the evening prayer; he would offer it along with the night prayer, he would delay the evening prayer; he would offer it along with the night prayer. If he moved off after the evening prayer, he would offer the night prayer earlier and offer it along with the evening prayer.
Abu Dawud said: This tradition has not been narrated by anyone except by Qutaibah.
I accompanied the Messenger of Allah (ﷺ) on eighteen journeys and I never saw him fail to pray two rak'ahs when the sun had passed the meridian before offering the noon prayer.
