When you travel in the land there is no sin if you curtail your service of prayer if you fear the unbelievers may harass you, for indeed your open enemies are the infidels. 101 And when thou (O Muhammad) art among them and arrangest (their) worship for them, let only a party of them stand with thee (to worship) and let them take their arms. Then when they have performed their prostrations let them fall to the rear and let another party come that hath not worshipped and let them worship with thee, and let them take their precaution and their arms. Those who disbelieve long for you to neglect your arms and your baggage that they may attack you once for all. It is no sin for you to lay aside your arms, if rain impedeth you or ye are sick. But take your precaution. Lo! Allah prepareth for the disbelievers shameful punishment. 102 When you have finished the prayer, remember God while standing, and sitting, and lying on your sides. When you feel secure, say your prayers in the prescribed form. Believers are under the obligation to say their prayers at the appointed hours. 103 And slacken not in following up the enemy: If ye are suffering hardships, they are suffering similar hardships; but ye have Hope from Allah, while they have none. And Allah is full of knowledge and wisdom. 104
