Sahih Bukhari

Narrated Jabir bin `Abdullah:`Umar bin Al-Khattab came on the day of Al-Khandaq after the sun had set and he was abusing the infidels of Quraish saying, ""O Allah's Messenger (ﷺ)! I was unable to offer the (`Asr) prayer till the sun was about to set."" The Prophet (ﷺ) said, ""By Allah, I have not offered this (i.e. `Asr) prayer."" So we came down along with the Prophet (ﷺ) to Buthan where he performed ablution for the prayer and then we performed the ablution for it. Then he offered the `Asr prayer after the sun had set, and after it he offered the Maghrib prayer
