Abu Wa'il reports: A man came to Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) and said: "Last night I recited a Mufassal surah in one rak'ah." Sayyiduna Abdullah said: "This has become like reciting poetry quickly. We remember, the Prophet (peace be upon him) used to combine similar surahs and recite them together." Then he mentioned the surahs related to the Mufassal. The Prophet (peace be upon him) used to recite two surahs in one rak'ah.
