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 thou art amongst them, and performest for them the prayer, let a party of them stand with thee, and let them take their weapons. When they bow themselves, let them be behind you; and let another party who have not prayed come and pray with thee, taking their precautions and their weapons. The unbelievers wish that you should be heedless of your weapons and your baggage, then they would wheel on you all at once. There is no fault in you, if rain molests you, or you are sick, to lay aside your weapons; but take your precautions. God has prepared for the unbelievers a humbling chastisement. 102 When you have finished the Prayer, remember Allah -standing, and sitting, and reclining. And when you become secure, perform the regular Prayer. The Prayer is enjoined upon the believers at stated times. 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
