When ye travel through the earth, there is no blame on you if ye shorten your prayers, for fear the Unbelievers May attack you: For the Unbelievers are unto you open 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 finished your prayer, remember God - standing and sitting and lying down; and when you are once again secure, observe your prayers [fully]. Verily, for all believers prayer is indeed a sacred duty linked to particular times [of day]. 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
