My father said, "The Prophet ﷺ used to recite Al-Fatiha along with another Sura in the first two rakʿat of the Zuhr and ʿAsr prayers. A verse or so was audible at times and he used to prolong the first rakʿa." (Using translation from Bukhārī 778)  

أَنَّ النَّبِيَّ ﷺ كَانَ «يَقْرَأُ بِأُمِّ الْقُرْآنِ وَبِسُورَتَيْنِ مَعَهَا فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ مِنْ صَلَاةِ الظُّهْرِ وَصَلَاةِ الْعَصْرِ وَيُسْمِعُنَا الْآيَةَ أَحْيَانًا وَكَانَ يُطَوِّلُ فِي الرَّكْعَةِ الْأُولَى»  

[Machine] From Yahya through his chain of narration, similar to it.  

عَنْ يَحْيَى بِإِسْنَادِهِ نَحْوَهُ  

[Machine] The Prophet ﷺ used to read in the first two units of the Dhuhr prayer Surat Al-Fatiha and two other Surahs. In the last two units, he used to read Surat Al-Fatiha only and he would make us hear the verse. He would prolong the first unit more than the second unit, and he would do the same in the Asr and Fajr prayers.  

أَنَّ النَّبِيَّ ﷺ كَانَ «يَقْرَأُ فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ مِنْ صَلَاةِ الظُّهْرِ بِأُمِّ الْكِتَابِ وَِسُورَتَيْنِ وَفِي الْأُخْرَيَيْنِ بِأُمِّ الْكِتَابِ وَكَانَ يُسْمِعُنَا الْآيَةَ وَكَانَ يُطِيلُ الرَّكْعَةِ الْأُولَى مَا لَا يُطِيلُ فِي الثَّانِيَةِ وَهَكَذَا فِي صَلَاةِ الْعَصْرِ وَهَكَذَا فِي صَلَاةِ الْغَدَاةِ»
