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."  

أَنَّ النَّبِيَّ ﷺ كَانَ يَقْرَأُ بِأُمِّ الْكِتَابِ وَسُورَةٍ مَعَهَا فِي الرَّكْعَتَيْنِ الأُولَيَيْنِ مِنْ صَلاَةِ الظُّهْرِ وَصَلاَةِ الْعَصْرِ وَيُسْمِعُنَا الآيَةَ أَحْيَانًا وَكَانَ يُطِيلُ فِي الرَّكْعَةِ الأُولَى
