My father said, "The Prophet ﷺ in Zuhr prayers used to recite Al-Fatiha along with two other Suras in the first two rakʿat: a long one in the first rakʿa and a shorter (Sura) in the second, and at times the verses were audible. In the ʿAsr prayer the Prophet ﷺ used to recite Al-Fatiha and two more Suras in the first two rakʿat and used to prolong the first rakʿa. And he used to prolong the first rakʿa of the Fajr prayer and shorten the second.  

كَانَ النَّبِيُّ ﷺ يَقْرَأُ فِي الرَّكْعَتَيْنِ الأُولَيَيْنِ مِنْ صَلاَةِ الظُّهْرِ بِفَاتِحَةِ الْكِتَابِ وَسُورَتَيْنِ يُطَوِّلُ فِي الأُولَى وَيُقَصِّرُ فِي الثَّانِيَةِ وَيُسْمِعُ الآيَةَ أَحْيَانًا وَكَانَ يَقْرَأُ فِي الْعَصْرِ بِفَاتِحَةِ الْكِتَابِ وَسُورَتَيْنِ وَكَانَ يُطَوِّلُ فِي الأُولَى وَكَانَ يُطَوِّلُ فِي الرَّكْعَةِ الأُولَى مِنْ صَلاَةِ الصُّبْحِ وَيُقَصِّرُ فِي الثَّانِيَةِ  

I asked Khabbab whether the Prophet ﷺ used to recite the Qur'an in the Zuhr and the ʿAsr prayers. He replied in the affirmative. We said, "How did you come to know that?" He said, "From the movement of his beard."  

سَأَلْنَا خَبَّابًا أَكَانَ النَّبِيُّ ﷺ يَقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ قَالَ نَعَمْ قُلْنَا بِأَىِّ شَىْءٍ كُنْتُمْ تَعْرِفُونَ قَالَ بِاضْطِرَابِ لِحْيَتِهِ
