Yusuf Ali
When thou (O Messenger) art with them, and standest to lead them in prayer, Let one party of them stand up (in prayer) with thee, Taking their arms with them: When they finish their prostrations, let them Take their position in the rear. And let the other party come up which hath not yet prayed - and let them pray with thee, Taking all precaution, and bearing arms: the Unbelievers wish, if ye were negligent of your arms and your baggage, to assault you in a single rush. But there is no blame on you if ye put away your arms because of the inconvenience of rain or because ye are ill; but take (every) precaution for yourselves. For the Unbelievers Allah hath prepared a humiliating punishment.

Sahih International
And when you are among them and lead them in prayer, let a group of them stand [in prayer] with you and let them carry their arms. And when they have prostrated, let them be [in position] behind you and have the other group come forward which has not [yet] prayed and let them pray with you, taking precaution and carrying their arms. Those who disbelieve wish that you would neglect your weapons and your baggage so they could come down upon you in one [single] attack. But there is no blame upon you, if you are troubled by rain or are ill, for putting down your arms, but take precaution. Indeed, Allah has prepared for the disbelievers a humiliating punishment.

Shakir
And when you are among them and keep up the prayer for them, let a party of them stand up with you, and let them take their arms; then when they have prostrated themselves let them go to your rear, and let another party who have not prayed come forward and pray with you, and let them take their precautions and their arms; (for) those who disbelieve desire that you may be careless of your arms and your luggage, so that they may then turn upon you with a sudden united attack, and there is no blame on you, if you are annoyed with rain or if you are sick, that you lay down your arms, and take your precautions; surely Allah has prepared a disgraceful chastisement for the unbelievers.

Pickthall
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.

محمد جالندھری
اور (اے پیغمبر) جب تم ان (مجاہدین کے لشکر) میں ہو اور ان کو نماز پڑھانے لگو تو چاہیئے کہ ان کی ایک جماعت تمہارے ساتھ مسلح ہو کر کھڑی رہے جب وہ سجدہ کرچکیں تو پرے ہو جائیں پھر دوسری جماعت جس نے نماز نہیں پڑھی (ان کی جگہ) آئے اور ہوشیار اور مسلح ہو کر تمہارے ساتھ نماز ادا کرے کافر اس گھات میں ہیں کہ تم ذرا اپنے ہتھیاروں اور سامان سے غافل ہو جاؤ تو تم پر یکبارگی حملہ کردیں اگر تم بارش کے سبب تکلیف میں یا بیمار ہو تو تم پر کچھ گناہ نہیں کہ ہتھیار اتار رکھو مگر ہوشیار ضرور رہنا خدا نے کافروں کے لئے ذلت کا عذاب تیار کر رکھا ہے
