[Machine] The Prophet ﷺ used to recite in the first two Rak'ahs of the Dhuhr prayer the opening chapter of the Quran and another chapter, and he would sometimes recite a verse that we could hear. He would also recite the opening chapter in the last two Rak'ahs of the prayer, and he would prolong his recitation in the first Rak'ah more than in the second Rak'ah. The same would apply to the Asr prayer and the Fajr prayer. This narration is reported in Sahih from the Hadith of Hammam ibn Yahya and others.
أَنَّ النَّبِيَّ ﷺ كَانَ يَقْرَأُ فِي صَلَاةِ الظُّهْرِ فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ بِفَاتِحَةِ الْكِتَابِ وَسُورَةٍ وَكَانَ يُسْمِعُنَا الْأَحْيَانَ الْآيَةَ قَالَ وَكَانَ يَقْرَأُ فِي الرَّكْعَتَيْنِ الْأُخْرَيَيْنِ بِفَاتِحَةِ الْكِتَابِ وَكَانَ يُطِيلُ فِي الرَّكْعَةِ الْأُولَى مَا لَا يُطِيلُ فِي الثَّانِيَةِ قَالَ وَهَكَذَا فِي صَلَاةِ الْعَصْرِ قَالَ وَهَكَذَا فِي صَلَاةِ الصُّبْحِ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ هَمَّامِ بْنِ يَحْيَى وَغَيْرِهِ
