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 (Muhammad), if you are among them (your followers during a battle) and you call them for prayer, let a group of them carry their arms during prayer. After they have made their prostrations, let them go back to watch the enemy and let the other group who has not yet prayed, join you, carrying their arms with due precaution. The unbelievers would love to find you neglecting your arms and property and would attack you suddenly. If rain or illness make you suffer, you may place your arms aside during prayer but still observe due precaution. God has prepared a humiliating torment for the unbelievers. 102 And when you have completed the prayer, remember Allah standing, sitting, or [lying] on your sides. But when you become secure, re-establish [regular] prayer. Indeed, prayer has been decreed upon the believers a decree of specified times. 103 Do not relent in the pursuit of the enemy. If you are suffering hardships, they too are suffering similar hardships, but what you can hope for from God, they cannot. God is all knowing and wise. 104
