Imam Ahmad reported that `Ali narrated that Allah's Messenger said during the battle of Al-Ahzab (the Confederates):

«شَغَلُونَا عَنِ الصَّلَاةِ الْوُسْطَى، صَلَاةِ الْعَصْرِ، مَلَأَ اللهُ قُلُوبَهُم وَبُيُوتَهم نَارًا»

(They (the disbelievers) busied us from performing the Middle prayer, the `Ar prayer, may Allah fill their hearts and houses with fire.)

He performed the `Asr prayer between Maghrib and `Isha'. Muslim and An-Nasa'i recorded this Hadith. In addition, the Two Shaykhs, Abu Dawud, At-Tirmidhi An-Nasa'i and several other collectors of the Sunan recorded this Hadith using different chains of narrators to `Ali. The Hadith about the battle of Al-Ahzab, when the Mushriks prevented Allah's Messenger and his Companions from performing the `Asr prayer, has been narrated by several other Companions. We only mentioned the narrations that stated that the Middle prayer is the `Asr prayer. Furthermore, Muslim reported similar wordings for this Hadith from Ibn Mas`ud and Al-Bara' bin `Azib.

In addition, Imam Ahmad reported that Samurah bin Jundub said that Allah's Messenger said:

«صَلَاةُ الْوسْطَى صَلَاةُ الْعَصْر»

(The Middle prayer is the `Asr prayer.)

In another narration, Allah's Messenger mentioned:

﴿حَـفِظُواْ عَلَى الصَّلَوَتِ والصَّلَوةِ الْوُسْطَى﴾

(Guard strictly (five obligatory) As-Salawat (the prayers) especially the Middle Salah) and stated that it is the `Asr prayer. In another narration, Allah's Messenger said:

«هِيَ الْعَصْر»

(It is the `Asr prayer.) and Ibn Ja`far mentioned that the Prophet was then being asked about the Middle prayer. At-Tirmidhi reported this Hadith and said, "Hasan, Sahih." In addition, Abu Hatim bin Hibban reported in his Sahih that `Abdullah said that Allah's Messenger said:

«صَلَاةُ الْوسْطَى صَلَاةُ الْعَصْر»

(The Middle prayer is the `Asr prayer.)

At-Tirmidhi reported that Ibn Mas`ud narrated that Allah's Messenger said:

«صَلَاةُ الْوسْطَى صَلَاةُ الْعَصْر»

(The `Asr prayer is the Middle prayer.)

At-Tirmidhi then stated that this Hadith is of a Hasan, Sahih type. Muslim reported the Hadith in his Sahih and his wordings are:

«شَغَلُونَا عَنِ الصَّلَاةِ الْوسْطَى صَلَاةِ الْعَصْر»

(They (disbelievers) busied us from performing the Middle prayer, the `Asr prayer.)

These texts emphasize the fact (that the `Asr prayer is the Middle prayer). What further proves this fact is that, in an authentic Hadith, Allah's Messenger emphasized the necessity of preserving the `Asr prayer, when he said, as Ibn `Umar narrated:

«مَنْ فَاتَتْهُ صَلَاةُ الْعَصْرِ فَكَأَنَّمَا وُتِرَ أَهْلَهُ وَمَالَه»

(Whoever misses the `Asr prayer will be like who has lost his family and money.)

It is reported in the Sahih that Buraydah bin Al-Husayb said that the Prophet said:

«بَكِّرُوا بِالصَّلَاةِ فِي يَوْمِ الْغَيْمِ، فَإِنَّهُ مَنْ تَرَكَ صَلَاةَ الْعَصْرِ، فَقَدْ حَبِطَ عَمَلُه»

(On a cloudy day, perform the (`Asr) prayer early, for whoever misses the `Asr prayer, will have his (good) deeds annulled.)
