Sunan an-Nasa'i, Volume 1, Book 7, Hadith 662 (DarusSalam) ⓘ

It was narrated from 'Abdur-Rahman bin Abi Sa'eed that his father said: "On the day of Al-Khandaq the idolators kept us from praying Zuhr until the sun had gone down; that was before the revelation concerning fighting was revealed. Then Allah, the Mighty and Sublime, revealed: Allah sufficed for the believers in the fighting.[1] The Messenger of Allah commanded Bilal to say the Iqamah for Zuhr prayer, and he offered it just as he used to offer it on time. Then he said the Iqamah for 'Asr and he offered it just as he used to offer it on time. Then he called the Adhan for Maghrib and offered it on time." [1] Al-Ahzab 33:25.

أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، قَالَ حَدَّثَنَا سَعِيدُ بْنُ أَبِي سَعِيدٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي سَعِيدٍ، عَنْ أَبِيهِ، قَالَ شَغَلَنَا الْمُشْرِكُونَ يَوْمَ الْخَنْدَقِ عَنْ صَلاَةِ الظُّهْرِ، حَتَّى غَرَبَتِ الشَّمْسُ وَذَلِكَ قَبْلَ أَنْ يَنْزِلَ فِي الْقِتَالِ مَا نَزَلَ فَأَنْزَلَ اللَّهُ عَزَّ وَجَلَّ ‏{‏ وَكَفَى اللَّهُ الْمُؤْمِنِينَ الْقِتَالَ ‏}‏ فَأَمَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم بِلاَلاً فَأَقَامَ لِصَلاَةِ الظُّهْرِ فَصَلاَّهَا كَمَا كَانَ يُصَلِّيهَا لِوَقْتِهَا ثُمَّ أَقَامَ لِلْعَصْرِ فَصَلاَّهَا كَمَا كَانَ يُصَلِّيهَا فِي وَقْتِهَا ثُمَّ أَذَّنَ لِلْمَغْرِبِ فَصَلاَّهَا كَمَا كَانَ يُصَلِّيهَا فِي وَقْتِهَا ‏.‏
