When you (O Messenger) are among the believers (who are on an expedition and in fear that the unbelievers might harm them) and stand (to lead) the Prayer for them, let a party of them stand in Prayer with you and retain their arms with them (while the other party maintain their positions against the enemy). When the first party have done the prostrations (finished the rak‘ah), let them go to the rear of your company (and there hold positions against the enemy), and let the other party who have not prayed come forward and pray with you, being fully prepared against danger and retaining their arms. Those who disbelieve wish that you should be heedless of your weapons and your equipment, so that they might swoop upon you in a single (surprise) attack. But there will be no blame on you if you lay aside your arms (during Prayer) if you are troubled by rain (and the ground impedes your movement), or if you are ill; however, be fully prepared against danger. Surely God has prepared for the unbelievers a shameful, humiliating punishment.
