When you travel in the land there is no sin if you curtail your service of prayer if you fear the unbelievers may harass you, for indeed your open enemies are the infidels. 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 And when you have completed the prayer, remember Allah standing, sitting, or [lying] on your sides. But when you become secure, re-establish [regular] prayer. Indeed, prayer has been decreed upon the believers a decree of specified times. 103 Relent not in pursuit of the enemy. If ye are suffering, lo! they suffer even as ye suffer and ye hope from Allah that for which they cannot hope. Allah is ever Knower, Wise. 104
