When you [believers] are travelling in the land, you will not be blamed for shortening your prayers, if you fear the disbelievers may harm you. They are your avowed enemies. 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 established the prayer, remember Allah standing, sitting, and on your sides. Then, when you are secure, establish the prayer, surely, prayer is timely written upon the believer. 103 And do not be chary of pursuing them. If you suffer, they shall also suffer like you. But while you have hope (of success) from God, they have none. Surely God is all-knowing and all-wise. 104
