We were in the company of the Prophet (ﷺ) on the day (of the battle) of Al-Khandaq (the Trench). The
Prophet said, "May Allah fill their (the infidels') graves and houses with fire, as they have kept us so
busy that we could not offer the middle prayer till the sun had set; and that prayer was the `Asr
prayer."
Sahih al-Bukhari Book 80, Hadith 91
