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: “Messenger of Allah صلی اللہ علیہ وآلہ وسلم, I was hardly able to pray until the sun set.” The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “By Allah, I did not pray.” So we went down with the Messenger of Allah صلی اللہ علیہ وآلہ وسلم to Buthan. He performed Wudufor prayer and so did we, and he prayed ‘Asr after the sun had set, then he prayed Maghrib after that.” (Sahih).
