[Machine] The Messenger of Allah ﷺ used to stand in the noon prayer for the first two units with the recitation of thirty verses in each unit. And in the last two units, he would recite fifteen verses in each unit. And he would stand in the afternoon prayer for the first two units with the recitation of fifteen verses in each unit. And in the last two units, he would recite half of that.
كَانَ رَسُولُ اللهِ ﷺ يَقُومُ فِي الظُّهْرِ فِي الرَّكْعَتَيْنِ الْأُولَيَيْنِ فِي كُلِّ رَكْعَةٍ قَدْرَ قِرَاءَةِ ثَلَاثِينَ آيَةً وَفِي الْأُخْرَيَيْنِ فِي كُلِّ رَكْعَةٍ قَدْرَ قِرَاءَةِ خَمْسَ عَشْرَةَ آيَةً وَكَانَ يَقُومُ فِي الْعَصْرِ فِي الرَّكْعَتَيْنِ الْأُولَتَيْنِ فِي كُلِّ رَكْعَةٍ قَدْرَ قِرَاءَةِ خَمْسَ عَشْرَةَ آيَةً وَفِي الْأُخْرَتَيْنِ قَدْرَ نِصْفِ ذَلِكَ
