Abu Qatada said that in the first two <i>rak'as</i> of the noon prayer the Prophet (ﷺ) used to recite <i>Umm al-Kitab</i> and two <i>suras</i>, and in the last two <i>rak'as</i> <i>Umm al-Kitab</i>, and he would sometimes recite loud enough for them to hear the verse. He would prolong the first <i>rak'a</i> more than the second; and he acted similarly in the afternoon and the Morning Prayer. (Bukhari and Muslim.)

وَعَنْ أَبِي قَتَادَةَ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يقْرَأ فِي الظُّهْرِ فِي الْأُولَيَيْنِ بِأُمِّ الْكِتَابِ وَسُورَتَيْنِ وَفِي الرَّكْعَتَيْنِ الْأُخْرَيَيْنِ بِأُمِّ الْكِتَابِ وَيُسْمِعُنَا الْآيَةَ أَحْيَانًا وَيطول فِي الرَّكْعَة الأولى مَا لَا يطول فِي الرَّكْعَةِ الثَّانِيَةِ وَهَكَذَا فِي الْعَصْرِ وَهَكَذَا فِي الصُّبْح
