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 performed the prayer, remember God, standing and sitting and on your sides. Then, when you are secure, perform the prayer; surely the prayer is a timed prescription for the believers. 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
