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 When you are among them, and have to lead the service of prayer, let one group stand up with you, but let them keep their arms. After they have paid their homage they should go to the rear, and let the group which has not done so yet offer their service of prayer with you, remaining cautious and armed, The infidels wish to find you neglectful of your arms and provisions, to attack you unawares. It will not be a sin if you put aside your arms when you are troubled by rain, or you are ill; but take full precautions. God has reserved for infidels a despicable punishment 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 slacken not in following up the enemy: If ye are suffering hardships, they are suffering similar hardships; but ye have Hope from Allah, while they have none. And Allah is full of knowledge and wisdom. 104
