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:

فَبِأَىِّ ءَالاءِ رَبِّكُمَا تُكَذِّبَانِ

Mankind and Jinn are surrounded by Divine Bounties

فَبِأَيِّ آلَاءِ رَ‌بِّكُمَا تُكَذِّبَانِ (So, [ 0 mankind and Jinn,] which of the bounties of your Lord will you deny?...55:13). The word آلَاءِ 'al a' is the plural and it means 'benefits, benefaction, favour, boon, blessing or bounty'. The address is to the two species of Jinn and men referred to in verse 33 below and many other verses of Surah Ar-Rahman where Jinn are specifically mentioned.
