A man came to Ibn Masʿud and said, "I recited the Mufassal (Suras) at night in one rakʿa." Ibn Masʿud said, "This recitation is (too quick) like the recitation of poetry. I know the identical Suras which the Prophet ﷺ used to recite in pairs." Ibn Masʿud then mentioned 20 Mufassal Suras including two Suras from the family of (i.e. those verses which begin with) Ha, Meem [??] (which the Prophet ﷺ used to recite) in each rakʿa.  

هَذًّا كَهَذِّ الشِّعْرِ لَقَدْ عَرَفْتُ النَّظَائِرَ الَّتِي كَانَ النَّبِيُّ ﷺ يَقْرِنُ بَيْنَهُنَّ فَذَكَرَ عِشْرِينَ سُورَةً مِنَ الْمُفَصَّلِ سُورَتَيْنِ فِي كُلِّ رَكْعَةٍ  

[Machine] "I read the detailed (passage) tonight in one unit (of prayer), and Abdullah said, 'Like this (poetry)?" I recognized the similar (verses) that the Messenger of Allah ﷺ used to recite in one unit (of prayer), so he mentioned twenty surahs from the beginning of the (passage) that connect between the two surahs."  

إِنِّي قَرَأْتُ الْمُفَصَّلَ اللَّيْلَةَ فِي رَكْعَةٍ فَقَالَ عَبْدُ اللهِ هَذًّا كَهَذِّ الشِّعْرِ؟ لَقَدْ عَرَفْتُ النَّظَائِرَ الَّتِي كَانَ يَقْرَؤُهَا رَسُولُ اللهِ ﷺ فِي رَكْعَةٍ فَذَكَرَ عِشْرِينَ سُورَةً مِنْ أَوَّلِ الْمُفَصَّلِ يَقْرِنُ بَيْنَ السُّورَتَيْنِ
