Sunan an-Nasa'i 1366

It was narrated from Jabir bin Abdullah that:On the Day of Al-Khandaq, after the sun had set, Umar bin Al-Khattab started cursing the disbelievers of the Quraish and said: "O Messenger of Allah, I was hardly able to pray until the sun set." The Messenger of Allah (ﷺ) said: "By Allah, I did not pray." So we went down with the Messenger of Allah (ﷺ) to Buthan. He performed wudu' for prayer and so did we, and he prayed 'Asr after the sun had set, then he prayed Maghrib after that
