Sunan Abi Dawud Book 4, Hadith 14
The Messenger of Allah (ﷺ) combined the noon and afternoon prayers, and the sunset and night prayers at Medina without any danger and rain. He was asked: What did he intend by it ? He replied: He intended that his community might not fall into hardship.
The Messenger of Allah (ﷺ) combined the noon and the afternoon prayers, and combined the sunset and night prayers without any danger or journey. Malik said: I think it so happened during rain.
Abu Dawud said: Hammad b. Salamah narrated it like manner from Abu al-Zubair, it has also been narrated by Qurrah b. Khalid from Abu al-Zubair. He said: It is so happened in a journey that we made to Tabuk.
The mu'adhdhin of Ibn Umar said: prayer (i.e. the time of prayer has come). He said: Go ahead. He then alighted before the disappearance. He then offered the night prayer. He then said: When the Messenger of Allah (ﷺ) was in a hurry about something, he would do as I did. Then he travelled and covered a distance of three days' journey on the day.
Abu Dawud said: A similar tradition has been transmitted by Ibn Jabir from Nafi' with the same chain.
