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

A man came to him and said: "Last night I recited Al-Mufassal in one rak'ah." He said: "That is like reciting poetry. But the Messenger of Allah ﷺ used to recite similar surahs, twenty surahs from Al-Mufassal, those that start with Ha-Mim."

إِنِّي قَرَأْتُ اللَّيْلَةَ الْمُفَصَّلَ فِي رَكْعَةٍ فَقَالَ هَذًّا كَهَذِّ الشِّعْرِ لَكِنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَقْرَأُ النَّظَائِرَ عِشْرِينَ سُورَةً مِنَ الْمُفَصَّلِ مِنْ آلِ حم

[AI] "This is like this poetry, but the Messenger of Allah ﷺ used to recite the equivalent of twenty Surahs from the Mufassal and the Alif Lam Meem family."

«هَذًّا كَهَذِّ الشِّعْرِ؟ لَكِنَّ رَسُولَ اللهِ ﷺ كَانَ» يَقْرَأُ النَّظَائِرَ عِشْرِينَ سُورَةً مِنَ الْمُفَصَّلِ وَآلِ حم
