On the day of Al-Khandaq (the battle of trench.) `Umar bin Al-Khattab came cursing the disbelievers
of Quraish after the sun had set and said, "O Allah's Messenger (ﷺ) I could not offer the `Asr prayer till the
sun had set." The Prophet (ﷺ) said, "By Allah! I, too, have not prayed." So we turned towards Buthan, and
the Prophet (ﷺ) performed ablution and we too performed ablution and offered the `Asr prayer after the
sun had set, and then he offered the Maghrib prayer.
