Fear Prayer

And the Statement of Allah تعالى: "And when you (Muslims) travel in the land, there is no sin on you if you shorten As-Salat (prayer) if you fear that the disbelievers may put you in trial (attack you etc.), verily the disbelievers are ever unto you open enemies. When you (O Messenger Muhammad ﷺ) are among them, and lead them in As-Salat (the prayer), let one party of them stand up (in Salat) with you taking their arms with them; when they finish their prostrations, let them take their position in the rear, and let the other party come up which has not yet offered Salat and let them offer Salat with you taking all precautions, and bearing arms. Those who disbelieve wish, if you were negligent of your arms and your baggage, to attack you in a single rush, 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. Verily! Allah has prepared a humiliating torment for the disbelievers. (V.4:101-102)

Al-Auza'i said, "If there are signs of victory and it is impossible to offer the Salat (prayer) then everyone should offer his Salat (prayer) with signs. If he cannot do even that then he can delay the Salat (prayer) till the battle is over or till they feel secure, then they can offer two Rak'at prayers. But if they are unable to complete the Salat (prayer) then they can perform one bowing and two prostrations (one Rak'a), and if they are unable to do even this, then saying Allahu-Akbar is not sufficient for them, and so they should postpone the Salat (prayer) till they feel secure." Mak-hul agrees to it (i.e. this verdict). And Anas bin Malik said, "I reached at dawn during the siege of Tustar and the fighting was at its peak. The Muslims were not able to offer the Fajr prayer and we did not offer Salat (prayer) till a part of the day had passed and then we offered the Salat with Abu Musa and we were granted victory by Allah." Anas further said, "It would not make me happy even if I got the whole world and whatever is in it instead of that Salat (prayer) (i.e. the one they missed because of fighting)." ​​

Al-Walid said: I told Al-Auza'i about the Salat (prayer) of Shurahbil bin As-Samt and his companions on the backs of animals. On that, he said, "That was the case with us if we feared that the time of Salat would be over." Al-Walid (disagreed with Al-Auza'i) deriving his verdict from the statement of the Prophet ﷺ: "None should offer the 'Asr prayer but at Bani Quraiza." ​​
