Hadith 3910

(حديث مرفوع) حَدَّثَنَا عَفَّانُ ، حَدَّثَنَا حَمَّادٌ ، حَدَّثَنَا عَاصِمٌ ، عَنْ زِرٍّ ، أَنَّ رَجُلًا قَالَ لِابْنِ مَسْعُودٍ : كَيْفَ تَعْرِفُ هَذَا الْحَرْفَ : مَاءٌ غَيْرُ يَاسِنٍ أَمْ آسِنٍ ؟ فَقَالَ : كُلَّ الْقُرْآنِ قَدْ قَرَأْتَ ؟ قَالَ : إِنِّي لَأَقْرَأُ الْمُفَصَّلَ أَجْمَعَ فِي رَكْعَةٍ وَاحِدَةٍ ، فَقَالَ : أَهَذَّ الشِّعْرِ لَا أَبَا لَكَ ؟ ! قَدْ عَلِمْتُ قَرَائِنَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الَّتِي كَانَ " يَقْرُنُ قَرِينَتَيْنِ ، قَرِينَتَيْنِ ؛ مِنْ أَوَّلِ الْمُفَصَّلِ " . وَكَانَ أَوَّلُ مُفَصَّلِ ابْنِ مَسْعُودٍ الرَّحْمَنُ .
Zirr says that once a man asked Sayyiduna Ibn Mas'ud (may Allah be pleased with him): How do you recite this verse: «مِنْ مَاءٌ غَيْرُ يَاسِنٍ» or «آسِنٍ» — with ya or with alif? Sayyiduna Ibn Mas'ud (may Allah be pleased with him) replied: Have you memorized the entire Qur'an except for this verse? He said: (You can estimate from this) I recite the Mufassalat in one rak'ah. Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: Like poetry? I also know examples where the Prophet (peace and blessings be upon him) recited two surahs in one rak'ah, both of which were from the Mufassalat. It should be noted that in the Mushaf of Sayyiduna Ibn Mas'ud (may Allah be pleased with him), the Mufassalat began from Surah Rahman.
