Bukhari

Narrated Nafi`: 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 Messenger (See Hadith No. 451, Vol 5 to know exactly "The Fear Prayer.")

Saeed bin Jubair said «وسع كرسيه‏» refers to the knowledge of the Lord. (This is an interpretive meaning; caution lies in accepting the apparent meaning and consigning the reality to Allah's knowledge.) «بسطة‏» means increase and excellence. «أفرغ‏» means "anzil" (send down), that is, "send down patience upon us." The word «ولا يئوده» means that there is no burden upon it. From this comes the word «آدني», meaning "he made me heavy (burdened me)." The words «آد» and «لأيد» refer to strength. The word «السنة » means drowsiness. «لم يتسنه‏» means "it did not become corrupt." The word «فبهت» means "will be defeated by argument." The word «خاوية‏» means "empty, where there is no companion." «عروشها» refers to its buildings. «ننشرها» means "we extract." The word «إعصار‏» means a violent wind that rises from the earth towards the sky like a pillar; it contains fire. Ibn Abbas (may Allah be pleased with them both) said the word «صلدا‏» means "smooth and clean, upon which nothing remains." And Ikrimah said the word «وابل‏» is used for heavy rain, and the word «طل» means dew. This is the example of a believer's good deed, that it does not go to waste. «يتسنه‏» means "to change, to become corrupt."
