Which was revealed in Makkah

Imam Ahmad recorded that Zirr said that a man said to Ibn Mas`ud: "How is this recited: "Ma'in Ghayri Yasin or Asin" He asked him, "Are you that proficient in reciting the whole Qur'an" He replied, "I recite the Mufassal section in one Rak`ah." So he said, "Woe to you! Do you recite the Qur'an in haste, as if it is poetry I know that the Prophet used to recite two Surahs from the beginning of the Mufassal section (in one Rak`ah)." And Ibn Mas`ud considered Surat Ar-Rahman to be the beginning of the Mufassal section. Abu `Isa At-Tirmidhi recorded that Jabir said, "The Messenger of Allah ﷺ went to his Companions and recited Surat Ar-Rahman from beginning to end for them, but they did not say anything. The Prophet said,

«لَقَدْ قَرَأْتُهَا عَلَى الْجِنِّ لَيْلَةَ الْجِنِّ فَكَانُوا أَحْسَنَ مَرْدُودًا مِنْكُمْ، كُنْتُ كُلَّمَا أَتَيْتُ عَلَى قَوْلِهِ:

أَلَّا تَطْغَوْا فِي الْمِيزَانِ (so that you should not be wrongful in weighing....55:8). The earlier verse stated the creation of the scale, and this verse states the reason for its creation. The imperfect verb تَطْغَوْا tatghaw is derived from طُغیَان tughyan which stands for 'injustice'. Thus verses [ 7] and [ 8] put together mean: '[ The 'mizan or scale' has been created so that you may not transgress the balance and thus practice injustice'.
