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:

وَأَقِيمُوا الْوَزْنَ بِالْقِسْطِ (And observe the correct weight with fairness, ....55:9). The word قِسط qist literally means 'justice'. The meaning is obvious: 'And observe the weight with equity'.

وَلَا تُخْسِرُ‌وا الْمِيزَانَ (and do not make weighing deficient...55:9). The word خُسر khusr means 'to skimp or make deficient'. The opening part of verse [ 9] was the positive aspect of the injunction, and the concluding part is its negative aspect, in that it is unlawful to fall short of measure or weight. The two parts, positive and negative, put together the verse as a whole means 'Do not cheat in weights and measures, but rather observe justice and fairness'.
