It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that a man came to him and said: O Abu Abdur-Rahman, how do you recite this verse: "of water unaltered"? Sayyiduna Abdullah (may Allah be pleased with him) said to him: "Have you memorised the whole Qur'an except this (one word)?" He said: I recite the mufassal surahs in a single rak'ah. At this Sayyiduna Abdullah (may Allah be pleased with him) said: "Is this rattling it off quickly like the reciting of poetry? Indeed, the best prayer is (performing well) the bowing and the prostration. And there will be people who recite the Qur'an but it will not go beyond their throats; but when the Qur'an is recited and it becomes firmly rooted in the heart, it benefits. I know well the matching surahs which the Messenger of Allah (peace and blessings be upon him) used to recite together in every rak'ah (of prayer)." Then Sayyiduna Abdullah (may Allah be pleased with him) got up and went inside, and Alqamah (may Allah have mercy on him) went in to him. Then the people said to Alqamah (may Allah have mercy on him): Ask him on our behalf about the matching surahs which the Messenger of Allah (peace and blessings be upon him) used to recite. So Alqamah (may Allah have mercy on him) came out to us and said: "They are twenty surahs of the mufassal, according to the arrangement and compilation of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him)."
