[Machine] The Messenger of Allah ﷺ used to lead us in prayer and recite in the first two units (rak'ahs) of Asr and Dhuhr with two surahs and the opening chapter of the Quran. He would sometimes recite a verse that we could hear. In the last two units (rak'ahs), he would recite the opening chapter of the Quran. He used to prolong the first rak'ah of the Fajr (dawn) prayer and the first rak'ah of the Dhuhr (noon) prayer.
كَانَ رَسُولُ اللهِ ﷺ يُصَلِّي بِنَا فَيَقْرَأُ فِي الْعَصْرِ وَالظُّهْرِ فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ بِسُورَتَيْنِ وَأُمِّ الْكِتَابِ وَكَانَ يُسْمِعُنَا الْأَحْيَانَ الْآيَةَ وَيَقْرَأُ فِي الرَّكْعَتَيْنِ الْأُخْرَيَيْنِ بِأُمِّ الْكِتَابِ وَكَانَ يُطِيلُ أَوَّلَ رَكْعَةٍ مِنْ صَلَاةِ الْفَجْرِ وَأَوَّلَ رَكْعَةٍ مِنْ صَلَاةِ الظُّهْرِ
