"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 ﷺ 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.  

عَنْ صَلاَةِ الظُّهْرِ حَتَّى غَرَبَتِ الشَّمْسُ وَذَلِكَ قَبْلَ أَنْ يَنْزِلَ فِي الْقِتَالِ مَا نَزَلَ فَأَنْزَلَ اللَّهُ ﷻ { وَكَفَى اللَّهُ الْمُؤْمِنِينَ الْقِتَالَ } فَأَمَرَ رَسُولُ اللَّهِ ﷺ 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  

[Machine] Regarding the prayers, it was mentioned that after Maghrib (sunset prayer) it became cool, and this was before descending for battle. So when we finished fighting, and this is in reference to Allah's statement, "And Allah was all sufficient for the believers in the battle" [Al-Ahzab 25], the Prophet ﷺ ordered Bilal to give the call to prayer (Adhan), then he established the Dhuhr (midday prayer) and prayed it as he would in its proper time. Then he established the 'Asr (afternoon prayer) and prayed it as he would in its proper time. Then he established the Maghrib (sunset prayer) and prayed it as he would in its proper time.  

عَنِ الصَّلَوَاتِ حَتَّى كَانَ بَعْدَ الْمَغْرِبِ هَوِيًّا وَذَلِكَ قَبْلَ أَنْ يَنْزِلَ فِي الْقِتَالِ مَا نَزَلَ فَلَمَّا كُفِينَا الْقِتَالَ وَذَلِكَ قَوْلُهُ {وَكَفَى اللهُ الْمُؤْمِنِينَ الْقِتَالَ وَكَانَ اللهُ قَوِيًّا عَزِيزًا} [الأحزاب 25] أَمَرَ النَّبِيُّ ﷺ بِلَالًا فَأَقَامَ الظُّهْرَ فَصَلَّاهَا كَمَا يُصَلِّيهَا فِي وَقْتِهَا ثُمَّ أَقَامَ الْعَصْرَ فَصَلَّاهَا كَمَا يُصَلِّيهَا فِي وَقْتِهَا ثُمَّ أَقَامَ الْمَغْرِبَ فَصَلَّاهَا كَمَا يُصَلِّيهَا فِي وَقْتِهَا
