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 And when you are among them and lead them in prayer, let a group of them stand [in prayer] with you and let them carry their arms. And when they have prostrated, let them be [in position] behind you and have the other group come forward which has not [yet] prayed and let them pray with you, taking precaution and carrying their arms. Those who disbelieve wish that you would neglect your weapons and your baggage so they could come down upon you in one [single] attack. But there is no blame upon you, if you are troubled by rain or are ill, for putting down your arms, but take precaution. Indeed, Allah has prepared for the disbelievers a humiliating punishment. 102 Then when ye have finished the prayer, remember Allah, standing and sitting and lying on your sides. Then when ye are secure, establish the prayer; verily the prayer is prescribed unto the believers at definite times. 103 Do not neglect the pursuit of the enemy. If you have suffered, they too have suffered but you can, at least, expect from God what they can never expect. God is All-knowing and All-wise. 104
