[Machine] The Messenger of Allah ﷺ forgot to pray the Dhuhr and Asr prayers on the day of the Battle of the Trench. He remembered after the Maghrib prayer and the Prophet ﷺ said, "They have kept us busy from prayer until the day is almost over. May Allah fill their graves with fire." He then prayed them after Maghrib.
أَنَّ رَسُولَ اللهِ ﷺ نَسِيَ صَلَاةَ الظُّهْرِ وَالْعَصْرِ يَوْمَ الْأَحْزَابِ فَذَكَرَ بَعْدَ الْمَغْرِبِ فَقَالَ النَّبِيُّ ﷺ «شَغَلُونَا عَنِ الصَّلَاةِ حَتَّى ذَهَبَ النَّهَارُ أَدْخَلَ اللهُ قُبُورَهُمْ نَارًا» فَصَلَّاهَا بَعْدَ الْمَغْرِبِ
