When you [believers] are travelling in the land, you will not be blamed for shortening your prayers, if you fear the disbelievers may harm you. They are your avowed enemies. 101 (O Messenger!) If you are among the believers and rise (in the state of war) to lead the Prayer for them, let a party of them stand with you to worship, keeping their arms. When they have performed their prostration, let them go behind you, and let another party who have not prayed, pray with you, remaining on guard and keeping their arms, for the unbelievers love to see you heedless of your arms and your baggage so that they might swoop upon you in a surprise attack. But there shall be no blame upon you if you were to lay aside your arms if you are either troubled by rain or are sick; but remain on guard. Surely Allah has prepared a humiliating chastisement for the unbelievers. 102 When you have finished the prayer, remember God while standing, and sitting, and lying on your sides. When you feel secure, say your prayers in the prescribed form. Believers are under the obligation to say their prayers at the appointed hours. 103 And be not faint of heart when you seek out the [enemy] host. If you happen to suffer pain, behold, they suffer pain even as you suffer it: but you are hoping [to receive] from God what they cannot hope for. And God is indeed all-knowing, wise. 104
