[Machine] O Abu Abdur-Rahman, how do you read this Ayah "{from unsullied water}" [Muhammad: 15], do you read it as ya or alif? So he said, "I have counted all of the Quran except for this one." Abdullah said, "I read the detailed one in each rakah." He said, "Abdullah did this as the poets do. Indeed, from the best of prayer is the rukoo and the sujood, and the Quran will be recited by people whose provision does not exceed their ankles. But when it is recited, it penetrates the heart and benefits. I definitely know the equivalent(s) which the Messenger of Allah ﷺ used to recite in two surahs in each rakah, then he stood and entered [prostration]. Alqamah came and entered [the prostration]. We said, Ask him about the equivalents which the Messenger of Allah ﷺ used to recite in each rakah." So he entered and asked him. Then he left and said, "Twenty surahs from the beginning of the Mufassal, in the compilation of Abdullah."
يَا أَبَا عَبْدِ الرَّحْمَنِ كَيْفَ تَقْرَأُ هَذِهِ الْآيَةَ {مِنْ مَاءٍ غَيْرِ آسِنٍ} [محمد 15] أَيَاءً تَقْرَأُهَا أَوْ أَلِفًا؟ فَقَالَ كُلُّ الْقُرْآنِ قَدْ أَحْصَيْتُ غَيْرَ هَذَا قَالَ إِنِّي لَأَقْرَأُ الْمُفَصَّلَ فِي رَكْعَةٍ فَقَالَ عَبْدُ اللهِ هَذًّا كَهَذِّ الشِّعْرِ إِنَّ مِنْ أَحْسَنِ الصَّلَاةِ الرُّكُوعَ وَالسُّجُودَ وَلَيَقْرَأَنَّ الْقُرْآنَ أَقْوَامٌ لَا يُجَاوِزُ تَرَاقِيَهُمْ وَلَكِنْ إِذَا قُرِئَ فَرَسَخَ فِي الْقَلْبِ نَفَعَ إِنِّي لَأَعْرِفُ النَّظَائِرَ الَّتِي كَانَ رَسُولُ اللهِ ﷺ يَقْرَأُ سُورَتَيْنِ فِي كُلِّ رَكْعَةٍ ثُمَّ قَامَ فَدَخَلَ فَجَاءَ عَلْقَمَةُ فَدَخَلَ فَقُلْنَا لَهُ سَلْهُ عَنِ النَّظَائِرِ الَّتِي كَانَ رَسُولُ اللهِ ﷺ يَقْرَأُ بِهَا فِي كُلِّ رَكْعَةٍ فَدَخَلَ فَسَأَلَهُ ثُمَّ خَرَجَ فَقَالَ عِشْرُونَ سُورَةً مِنْ أَوَّلِ الْمُفَصَّلِ فِي تَأْلِيفِ عَبْدِ اللهِ
