Imam Ahmad recorded that Abu `Ayyash Az-Zuraqi said, "We were with the Messenger
of Allah in the area of `Usfan (a well known place near Makkah), when the idolators
met us under the command of Khalid bin Al-Walid, and they were between us and the
Qiblah. The Messenger of Allah led us in Zuhr prayer, and the idolators said, `They
were busy with something during which we had a chance to attack them.' They then
said, `Next, there will come a prayer (`Asr) that is dearer to them than their children
and themselves.' However, Jibril came down with these Ayat between the prayers of
Zuhr and `Asr,
﴿وَإِذَا كُنتَ فِيهِمْ فَأَقَمْتَ
لَهُمُ الصَّلَوةَ﴾
(When you (O Messenger Muhammad ) are among them, and lead them in Salah (prayer)).
When the time for prayer came, the Messenger of Allah commanded Muslims to hold
their weapons and he made us stand in two lines behind him. When he bowed, we all
bowed behind him. When he raised his head, we all raised our heads. The Prophet
then prostrated with the line that was behind him while the rest stood in guard.
When they finished with the prostration and stood up, the rest sat and performed
prostration, while those who performed it stood up in guard after the two lines
exchanged position. The Prophet then bowed and they all bowed after him, then raised
their heads after he raised his head. Then the Prophet performed prostration with
the line that was behind him, while the rest stood in guard. When those who made
prostration sat, the rest prostrated. The Prophet then performed the Taslim and
ended the prayer. The Messenger of Allah performed this prayer twice, once in `Usfan
and once in the land of Banu Sulaym.''' This is the narration recorded by Abu Dawud
and An-Nasa'i, and it has an authentic chain of narration and many other texts to
support it. Al-Bukhari recorded that Ibn `Abbas said, "Once the Prophet led the
Fear prayer and the people stood behind him. He said Allahu-Akbar and the people
said the same. He bowed and some of them bowed. Then he prostrated and they also
prostrated. Then he stood for the second Rak`ah and those who had prayed the first
Rak`ah left and guarded their brothers. The second party joined him and performed
bowing and prostration with him. All the people were in prayer, but they were guarding
one another during the prayer.'' Imam Ahmad recorded that Jabir bin `Abdullah said
that the Messenger of Allah led them in the Fear prayer. A group of them stood before
him and a group behind him. The Prophet led those who were behind him with one Rak`ah
and two prostrations. They then moved to the position of those who did not pray,
while the others stood in their place, and the Messenger of Allah performed one
Rak`ah and two prostrations and then said the Salam. Therefore, the Prophet prayed
two Rak`ah while they prayed one. An-Nasa'i recorded this Hadith, while Muslim collected
other wordings for it. Collectors of the Sahih, Sunan and Musnad collections recorded
this in a Hadith from Jabir. Ibn Abi Hatim recorded that Salim said that his father
said,
﴿وَإِذَا كُنتَ فِيهِمْ فَأَقَمْتَ
لَهُمُ الصَّلَوةَ﴾
(When you (O Messenger Muhammad ) are among them, and lead them in Salah (prayer))
refers to the Fear prayer. The Messenger of Allah led one group and prayed one Rak`ah,
while the second group faced the enemy. Then the second group that faced the enemy
came and Allah's Messenger led them, praying one Rak`ah, and then said the Salam.
Each of the two groups then stood up and prayed one more Rak`ah each (while the
other group stood in guard).'' The Group collected this Hadith with Ma`mar in its
chain of narrators. This Hadith also has many other chains of narration from several
Companions, and Al-Hafiz Abu Bakr Ibn Marduwyah collected these various narrations,
as did Ibn Jarir. As for the command to hold the weapons during the Fear prayer,
a group of scholars said that it is obligatory according to the Ayah. What testifies
to this is that Allah said;
﴿وَلاَ جُنَاحَ عَلَيْكُمْ إِن كَانَ
بِكُمْ أَذًى مِّن مَّطَرٍ أَوْ كُنتُم مَّرْضَى أَن تَضَعُواْ أَسْلِحَتَكُمْ وَخُذُواْ
حِذْرَكُمْ﴾
(But there is no sin on you if you put away your arms because of the inconvenience
of rain or because you are ill, but take every precaution for yourselves) meaning,
so that when necessary, you will be able to get to your weapons easily,
﴿إِنَّ اللَّهَ أَعَدَّ لِلْكَـفِرِينَ
عَذَاباً مُّهِيناً﴾
(Verily, Allah has prepared a humiliating torment for the disbelievers).
﴿فَإِذَا قَضَيْتُمُ
الصَّلَوةَ فَاذْكُرُواْ اللَّهَ قِيَـماً وَقُعُوداً وَعَلَى جُنُوبِكُمْ فَإِذَا
اطْمَأْنَنتُمْ فَأَقِيمُواْ الصَّلَوةَ إِنَّ الصَّلَوةَ كَانَتْ عَلَى الْمُؤْمِنِينَ
كِتَـباً مَّوْقُوتاً - وَلاَ تَهِنُواْ فِى ابْتِغَآءِ الْقَوْمِ إِن تَكُونُواْ تَأْلَمُونَ
فَإِنَّهُمْ يَأْلَمُونَ كَمَا تَأْلَمونَ وَتَرْجُونَ مِنَ اللَّهِ مَا لاَ يَرْجُونَ
وَكَانَ اللَّهُ عَلِيماً حَكِيماً ﴾
(103. When you have finished the Salah, remember Allah standing, sitting down, and
on your sides, but when you are free from danger, perform the Salah. Verily, Salah
is kitaban on the believers at fixed hours.) (104. And don't be weak in the pursuit
of the enemy; if you are suffering (hardships) then surely they (too) are suffering
(hardships) as you are suffering, but you have a hope from Allah (for the reward,
i.e. Paradise) that for which they hope not; and Allah is Ever All-Knowing, All-Wise.)
