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 the believers and lead them in prayer, let only part of them stand up along with you, armed with their weapons. After they have prostrated themselves, let them withdraw to the rear to stand guard and then let another party, who have not yet prayed, come forward and pray with you. And let them also be on their guard, armed with their weapons. Those who deny the truth want you to be negligent of your arms and your baggage, so that they may fall upon you suddenly. It is no offence for you to lay aside your arms when overtaken by heavy rain or illness, and always take every precaution for defence. God has prepared a humiliating punishment for those who deny the truth. 102 When you have established the prayer, remember Allah standing, sitting, and on your sides. Then, when you are secure, establish the prayer, surely, prayer is timely written upon the believer. 103 And do not be weak in seeking out the people. If you are suffering, they are also suffering as you are suffering, but you are hoping from Allah that which they do not hope. Allah is the Knower, the Wise. 104
