And when you (Muslims) travel in the land, there is no sin on you if you shorten your Salat (prayer) if you fear that the disbelievers may attack you, verily, the disbelievers are ever unto you open 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 Then when you have finished the prayer, remember Allah standing and sitting and reclining; but when you are secure (from danger) keep up prayer; surely prayer is a timed ordinance for the believers. 103 And don't be weak in the pursuit of the enemy; if you are suffering (hardships) then surely, they (too) are suffering (hardships) as you are suffering, but you have a hope from Allah (for the reward, i.e. Paradise) that for which they hope not, and Allah is Ever All-Knowing, All-Wise. 104
