Whenever `Abdullah bin `Umar was asked about Salat-al-Khauf (i.e. prayer of fear) he said, "The Imam comes forward with a group of people and leads them in a one rak`a prayer while another group from them who has not prayed yet, stay between the praying group and the enemy. When those who are with the Imam have finished their one rak`a, they retreat and take the positions of those who have not prayed but they will not finish their prayers with Taslim. Those who have not prayed, come forward to offer a rak`a with the Imam (while the first group covers them from the enemy). Then the Imam, having offered two rak`at, finishes his prayer. Then each member of the two groups offer the second rak`a alone after the Imam has finished his prayer. Thus each one of the two groups will have offered two rak`at. But if the fear is too great, they can pray standing on their feet or riding on their mounts, facing the Qibla or not." Nafi` added: I do not think that `Abdullah bin `Umar narrated this except from Allah's Apostle (See Hadith No. 451, Vol 5 to know exactly "The Fear Prayer.")

This hadith has been narrated by another chain of transmitters.

Concerning those who witnessed the Fear Prayer that was performed in the battle of Dhat-ur-Riqa' in the company of Allah's Apostle; One batch lined up behind him while another batch (lined up) facing the enemy. The Prophet led the batch that was with him in one rak`a, and he stayed in the standing posture while that batch completed their (two rak`at) prayer by themselves and went away, lining in the face of the enemy, while the other batch came and he (i.e. the Prophet) offered his remaining rak`a with them, and then, kept on sitting till they completed their prayer by themselves, and he then finished his prayer with Taslim along with them.

Yazid b. Ruman told on the authority of Salih b. Khawwat on the authority of one who prayed in time of danger with Allah's Messenger (may peace he upon him) at the Battle of Dhat ar-Riqa' that a group formed a row and prayed along with him, and a group faced the enemy. He led the group which was along with him in a rak'ah, then remained standing while they finished the prayer by themselves. Then they departed and formed a row facing the enemy. Then the second group came and he led them in the remaining rak'ah, after which he remained seated while they finished the prayer themselves. He then led them in salutation.

Abu Salama b. 'Abd al-Rahman reported that Jabir told him that he had observed the prayer in danger with the Messenger of Allah (may peace be upon him). The Messenger of Allah (may peace be upon him) (first) led one of the two groups in two rak'ah of prayer. and then led the second group in two rak'ah of prayer. So the Messenger of Allah (may peace be upon him) observed four rak'ah and led in two rak'ah each of the groups.

Sahl b. Abu Hathma reported that the Messenger of Allah (may peace be upon him) led his Companions in prayer in danger. He made them stand in two rows behind him. He led them who were close to him in one rak'ah. He then stood up and kept standing till those who were behind them observed one rak'ah. Then they (those standing in the second row) came in front and those who were in front went into the rear. He then led them In one rak'ah. He then sat down, till those who were behind him observed one rak'ah and then pronounced salutation.

I asked Az-Zuhri, "Did the Prophet ever offer the Fear Prayer?" Az-Zuhri said, "I was told by Salim that `Abdullah bin `Umar I had said, 'I took part in a holy battle with Allah's Apostle I in Najd. We faced the enemy and arranged ourselves in rows. Then Allah's Apostle (p.b.u.h) stood up to lead the prayer and one party stood to pray with him while the other faced the enemy. Allah's Apostle (p.b.u.h) and the former party bowed and performed two prostrations. Then that party left and took the place of those who had not prayed. Allah's Apostle prayed one rak`a (with the latter) and performed two prostrations and finished his prayer with Taslim. Then everyone of them bowed once and performed two prostrations individually.' "

Yahya related to me from Malik from Abu'z Zubayr al-Makki from Said ibn Jubayr that Abdullah ibn Abbas said, "The Messenger of Allah, may Allah bless him and grant him peace, prayed dhuhr and asr together and maghrib and isha together, and not out of fear nor because of travelling."

If anyone hears him who makes the call to prayer and is not prevented from joining the congregation by any excuse--he was asked what an excuse consisted of and replied that it was fear or illness--the prayer he offers will not be accepted from him.

Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab said, "The Messenger of Allah, may Allah bless him and grant him peace, did not pray dhuhr and asr on the day of the Trench until after the sun had set."

Malik said, "The hadith of al- Qasim ibn Muhammad from Salih ibn Khawwat is the one I like most out of what I have heard about the fear prayer."
