Allah (may He be glorified and exalted) has enjoined us to reflect upon the Qur’an, as He says: {[This is] a blessed Book which We have revealed to you, [O Muhammad], that they might reflect upon its verses and that those of understanding would be reminded} [Sad 38:29] and {Then do they not reflect upon the Qur’an?} [al-Nisa’ 4:82]. This is the purpose behind reciting it; it is not right to merely pronounce its letters without understanding or reflection. This is further emphasized if the recitation is in prayer. In this hadith, we see that ‘Abdullah ibn Mas‘ud (may Allah be pleased with him) disliked the action of this man who said to him that he had recited all of al-Mufassal in one rak‘ah. Al-Mufassal includes the surahs from Qaf to the end of the Qur’an, or from Surat Muhammad to the end of the Qur’an. It is called mufassal because its surahs are short and are separated (infisal) from one another with frequent intervals. Ibn Mas‘ud (may Allah be pleased with him) objected to what this man did and said to him: This is like reciting poetry. In other words, his recitation was quick, without reflection, as is done when reciting poetry. He only said that because this manner of reciting was customary among them when reciting poetry. Here Ibn Mas‘ud (may Allah be pleased with him) was denouncing the man’s action because it indicated a lack of reflection on what he was reciting. But if the worshipper recites at a moderate pace whilst reflecting on the meaning, then standing for a longer time increases his reward. Then Ibn Mas‘ud (may Allah be pleased with him) stated that he knew the pairs of surahs that were similar in length, that the Prophet (blessings and peace of Allah be upon him) used to recite together in prayer, reciting two surahs in each rak‘ah. The number of these surahs was thirty, from al-Mufassal. These surahs are mentioned in a report narrated by Abu Dawud, from Ibn Mas‘ud (may Allah be pleased with him). They are: al-Rahman and al-Najm in one rak‘ah; al-Qamar and al-Haqqah in one rak‘ah; al-Tur and al-Dhariyat in one rak‘ah; al-Waqi‘ah and al-Qalam in one rak‘ah; al-Ma‘arij and al-Nazi‘at in one rak‘ah; al-Mutaffifeen and ‘Abasa in one rak‘ah; al-Muddaththir and al-Muzzammilin one rak‘ah; al-Insan and al-Qiyamahin one rak‘ah; al-Naba’ and al-Mursalat in one rak‘ah; al-Dukhan and al-Takwir in one rak‘ah. If someone were to say: al-Dukhan is not part of al-Mufassal, so how can it be included as being part of al-Mufassal? The answer is that it is by way of convenience. In one report it says: Eighteen surahs from al-Mufassal and two surahs from the “family of Ha-Mim” [i.e., the surahs that begin with Ha-Mim]. This hadith indicates that it is permissible to recite two or more surahs in one rak‘ah..
