AND WHEN you go forth [to war] on earth, you will incur no sin by shortening your prayers if you have reason to fear that those who are bent on denying the truth might suddenly fall upon you: for, verily, those who deny the truth are your open foes. 101 (Muhammad), if you are among them (your followers during a battle) and you call them for prayer, let a group of them carry their arms during prayer. After they have made their prostrations, let them go back to watch the enemy and let the other group who has not yet prayed, join you, carrying their arms with due precaution. The unbelievers would love to find you neglecting your arms and property and would attack you suddenly. If rain or illness make you suffer, you may place your arms aside during prayer but still observe due precaution. God has prepared a humiliating torment for the unbelievers. 102 When you have performed the prayer, remember God, standing and sitting and on your sides. Then, when you are secure, perform the prayer; surely the prayer is a timed prescription for the believers. 103 Do not be faint of heart in pursuing these people: if you happen to suffer harm they too are suffering just as you are, while you may hope from Allah what they cannot hope for. Allah is All-Knowing, All- Wise. 104
