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 Then when you have finished the prayer, remember Allah standing and sitting and reclining; but when you are secure (from danger) keep up prayer; surely prayer is a timed ordinance for the believers. 103 And be not weak hearted in pursuit of the enemy; if you suffer pain, then surely they (too) suffer pain as you suffer pain, and you hope from Allah what they do not hope; and Allah is Knowing, Wise. 104
