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 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 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 don't be weak in the pursuit of the enemy; if you are suffering (hardships) then surely, they (too) are suffering (hardships) as you are suffering, but you have a hope from Allah (for the reward, i.e. Paradise) that for which they hope not, and Allah is Ever All-Knowing, All-Wise. 104
