´It was narrated that Abu Sa'eed Al-Khudri said:` "We used to estimate how long the Messenger of Allah (ﷺ) stood when praying in Zuhr and 'Asr. We estimated that he stood in Zuhr for as long as it take to recite thirty verses, as long as Surat As-Sajadah in the fits two Rak'ahs, and half that in the last two. And we estimated that he stood for as long in the fits two Rak'ahs, and half that in the last two. And we estimated that he stood for as long in the first two Rak'ahs of 'Asr as he stood in the last two Rak'ahs of Zuhr, and we estimated that he stood half as long as that in the last two Rak'ahs of 'Asr."

476. Commentary: Along with knowing the number of rak‘ahs of the ‘Asr prayer, it is also understood that the Prophet (sallallahu alayhi wa sallam) would recite only al-Fatihah in the last two rak‘ahs of ‘Asr, and would not add any other surah. However, in the last two rak‘ahs of Dhuhr, he would recite another surah along with Surah al-Fatihah. Thus, it is permissible to recite only al-Fatihah in the last two rak‘ahs of an obligatory (fard) prayer, and if another surah is added, there is no harm in it.

´It was narrated that Abu Sa'eed Al-Khudri said:` "The Messenger of Allah (ﷺ) used to stand in Zuhr and recite the equivalent of thirty verses in each Rak'ah, then in the first two Rak'ahs of 'Asr he would stand for the equivalent of fifteen verses."
Hafiz Muhammad Ameen
477. Commentary: By «فِيكُلِّرَكْعَة» is meant that in each of the first two rak‘ahs, he would recite approximately the equivalent of thirty verses, not that thirty verses would be recited in each of the four rak‘ahs. This is because this meaning is understood from the detailed narrations.

Abu Saeed Al Khudri said: We used to estimate how long the Messenger of Allah ﷺ stood in the noon and the afternoon prayer, and we estimated that he stood in the first two rak’ahs of the noon prayer as long as it takes to recite thirty verses (of the Quran), such as A-L-M Tanzil al-Sajdah. And we estimated that he stood in the last two rak’ahs half the time he stood in the first two rak’ahs. We estimated that he stood in the first two rak’ahs of the afternoon prayer as long as he did in the last two at noon; and we estimated that he stood in the last two rak’ahs of the afternoon prayer half the time he did in first two.
Shaykh Umar Farooq Saeedi
804. Commentary: It is understood that in the prayers of Dhuhr and Asr, recitation (qira’ah) is done in all four rak‘ahs. That is, along with Surah al-Fatihah, any other surah may also be recited. However, it is preferable that the latter rak‘ahs be light and brief.
