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 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 So when you have offered your prayers remember Allah while standing, sitting and reclining; and when you feel secure, offer prayers in the usual manner; indeed prayers are a time bound obligatory duty upon the Muslims. 103 And do not weaken in pursuit of the enemy. If you should be suffering - so are they suffering as you are suffering, but you expect from Allah that which they expect not. And Allah is ever Knowing and Wise. 104
