4:102

وَإِذَا كُنتَ فِيهِمْ فَأَقَمْتَ لَهُمُ الصَّلَاةَ فَلْتَقُمْ طَائِفَةٌ مِّنْهُم مَّعَكَ وَلْيَأْخُذُوا أَسْلِحَتَهُمْ فَإِذَا سَجَدُوا فَلْيَكُونُوا مِن وَرَائِكُمْ وَلْتَأْتِ طَائِفَةٌ أُخْرَىٰ لَمْ يُصَلُّوا فَلْيُصَلُّوا مَعَكَ وَلْيَأْخُذُوا حِذْرَهُمْ وَأَسْلِحَتَهُمْ وَدَّ الَّذِينَ كَفَرُوا لَوْ تَغْفُلُونَ عَنْ أَسْلِحَتِكُمْ وَأَمْتِعَتِكُمْ فَيَمِيلُونَ عَلَيْكُم مَّيْلَةً وَاحِدَةً وَلَا جُنَاحَ عَلَيْكُمْ إِن كَانَ بِكُمْ أَذًى مِّن مَّطَرٍ أَوْ كُنتُم مَّرْضَىٰ أَن تَضَعُوا أَسْلِحَتَكُمْ وَخُذُوا حِذْرَكُمْ إِنَّ اللَّهَ أَعَدَّ لِلْكَافِرِينَ عَذَابًا مُّهِينًا

Word by Word:

And when you are among them and you lead for them the prayer, then let stand a group of them with you and let them their arms. Then when they have prostrated, then let them be behind you and let come (forward) a group - other, (which has) not prayed, and let them with you and let them their precautions and their arms. Wished those who disbelieved if you neglect [about] your arms and your baggage so (that) they (can) assault [upon] you (in) a single attack. But (there is) no blame upon you if was with you any trouble (because) of rain or you are sick that you lay down your arms, but take your precautions. Indeed, Allah has prepared for the disbelievers a punishment humiliating.

Translations:

Thus, when thou art among the believers and about to lead them in prayer, let [only] part of them stand up with thee, retaining their arms. Then, after they have finished their prayer, let them provide you cover while another group, who have not yet prayed, shall come forward and pray with thee, being fully prepared against danger and retaining their arms: (for) those who are bent on denying the truth would love to see you oblivious of your arms and your equipment, so that they might fall upon you in a surprise attack. But it shall not be wrong for you to lay down your arms [while you pray] if you are troubled by rain or if you are ill; but [always] be fully prepared against danger. Verily, God has readied shameful suffering for all who deny the truth!

When thou (O Apostle) 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 o n 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 God hath prepared a humiliating punishment.

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.

And when thou art among them and leadest the prayer for them, let a party of them stand up with thee, and let them take their arms. Then when they have performed their prostration, let them go to your rear, and let another party who have not prayed come forward and pray with thee, and let them take their precautions and their arms. Those who disbelieve long that you may neglect your arms and your baggage, that they may attack you with a sudden united attack. And there is no blame on you, if you are inconvenienced on account of rain or if you are sick, to put away your arms; and take your precautions. Surely Allah has prepared abasing chastisement for the disbelievers.

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.
