Sahih al-Bukhari 598

Narrated Jabir:

`Umar came cursing the disbelievers (of Quraish) on the day of Al-Khandaq (the battle of Trench) and said, "I could not offer the `Asr prayer till the sun had set. Then we went to Buthan and he offered the (`Asr) prayer after sunset and then he offered the Maghrib prayer.

حَدَّثَنَا مُسَدَّدٌ، قَالَ حَدَّثَنَا يَحْيَى، عَنْ هِشَامٍ، قَالَ حَدَّثَنَا يَحْيَى ـ هُوَ ابْنُ أَبِي كَثِيرٍ ـ عَنْ أَبِي سَلَمَةَ، عَنْ جَابِرٍ، قَالَ جَعَلَ عُمَرُ يَوْمَ الْخَنْدَقِ يَسُبُّ كُفَّارَهُمْ وَقَالَ مَا كِدْتُ أُصَلِّي الْعَصْرَ حَتَّى غَرَبَتْ‏.‏ قَالَ فَنَزَلْنَا بُطْحَانَ، فَصَلَّى بَعْدَ مَا غَرَبَتِ الشَّمْسُ، ثُمَّ صَلَّى الْمَغْرِبَ‏.‏
