Times of the Prayers
The Qada of prayers (Qada means to perform or offer or do a missed religious obligation after its stated time)
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.
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.
