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 (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 Relent not in pursuit of the enemy. If ye are suffering, lo! they suffer even as ye suffer and ye hope from Allah that for which they cannot hope. Allah is ever Knower, Wise. 104
