When you are on a journey, it is no sin to shorten your prayers if you are afraid of the mischief of the unbelievers. The unbelievers have always been your sworn 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 When ye pass (Congregational) prayers, celebrate Allah's praises, standing, sitting down, or lying down on your sides; but when ye are free from danger, set up Regular Prayers: For such prayers are enjoined on believers at stated times. 103 Do not be faint of heart in pursuing these people: if you happen to suffer harm they too are suffering just as you are, while you may hope from Allah what they cannot hope for. Allah is All-Knowing, All- Wise. 104
