Ibn Abi Hatim recorded that Abu Hurayrah said,

[وَالْمُرْسَلَـتِ عُرْفاً ]

(By the Mursalat `Urfa.) "The angels.'' From Masruq, Abu Ad-Duha, Mujahid in one narrations from him, As-Suddi and Ar-Rabi` bin Anas, statements similar to this have been reported. It has been reported from Abu Salih that he said, "These are the Messenger.'' In another narration from him (Abu Salih) he said that it means the angels. Abu Salih has also said the meaning of Al-`Asifat, An-Nashirat, Al-Fariqat and Al-Mulqiyat, that they all refer to the angels. Ath-Thawri narrated from Salamah bin Kuhayl, who reported from Muslim Al-Batin, who reported from Abu Al-`Ubaydayn that he asked Ibn Mas`ud about the meaning of Al-Mursalat `Urfa, and he (Ibn Mas`ud) said, "The wind.'' He said the same about Al-`Asifat `Asfa and An-Nashirat Nashra, that they all refer to the wind. Ibn `Abbas, Mujahid and Qatadah all said the same. Ibn Jarir confidently affirmed that Al-`Asifat `Asfa means the wind just as Ibn Mas`ud and those who followed him said.However, he (Ibn Jarir) did not affirm whether An-Nashirat Nashra are the angels or the wind as has preceded. It has been reported from Abu Salih that An-Nashirat Nashra is the rain. The most obvious meaning is as Allah says,

[وَأَرْسَلْنَا الرِّيَاحَ لَوَاقِحَ]

(And we send the winds fertilizing.) (15:22) He also says,

[وَهُوَ الَّذِى يُرْسِلُ الرِّيَاحَ بُشْرىً بَيْنَ يَدَىْ رَحْمَتِهِ]

(And it is He Who sends the winds as heralds of glad tidings, going before His mercy (rain).) (7:57) Similarly, Al-`Asifat are winds. It is said (in Arabic) that the winds `Asifat when they make noise with their blowing. Likewise, An-Nashirat are the winds that scatter into clouds in the horizons of the sky according to the will of the Lord. Allah then says,

[فَالْفَـرِقَـتِ فَرْقاً - فَالْمُلْقِيَـتِ ذِكْراً - عُذْراً أَوْ نُذْراً ]

(The Fariqat that separate, the Mulqiyat that remind, excusing or warning.) meaning, the angels. This was said by Ibn Mas`ud, Ibn `Abbas, Masruq, Mujahid, Qatadah, Ar-Rabi` bin Anas, As-Suddi and Ath-Thawri. There is no difference of opinion here, because they (the angels) are the ones who descend with Allah's command to the Messengers, separating between the truth and falsehood, guidance and misguidance, and the lawful and the forbidden. They bring the revelation to the Messengers, which contains exemption or absolvement for the creatures and a warning for them of Allah's torment if they oppose His command. Allah said,

[إِنَّمَا تُوعَدُونَ لَوَقِعٌ ]

(Surely, what you are promised will occur.) This is the subject of these oaths. This means, what you all have been promised concerning the establishment of the Hour (Judgement Day), the blowing of the horn, the resurrection of the bodies, the gathering of those of old and those of latter times on one common ground and the rewarding of every doer of a deed based upon his deed. If he did good, then his reward will be good, and if he did evil, then his reward will be evil. All of this will occur, meaning it will come to pass and there is no avoiding it.
