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 And when you (O dear Prophet Mohammed – peace and blessings be upon him) are among them and lead them in prayer, only a group of them should be with you, and they must keep their weapons with them; so when they have performed their prostrations they should move away behind you; and the other group that had not prayed, must come and offer prayers in your leadership, keeping their guard and weapons with them; the disbelievers wish that you neglect your arms and your means so they may overpower you with a single attack; it is no sin for you to lay aside your arms due to rain or if you are sick; and keep your guard; undoubtedly Allah has kept prepared a disgraceful punishment for the disbelievers. 102 And when you have finished your prayer, remember God - standing and sitting and lying down; and when you are once again secure, observe your prayers [fully]. Verily, for all believers prayer is indeed a sacred duty linked to particular times [of day]. 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
