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 Then when ye have finished the prayer, remember Allah, standing and sitting and lying on your sides. Then when ye are secure, establish the prayer; verily the prayer is prescribed unto the believers at definite times. 103 And do not be weak in seeking out the people. If you are suffering, they are also suffering as you are suffering, but you are hoping from Allah that which they do not hope. Allah is the Knower, the Wise. 104
