وَاِذَا كُنْتَ فٖیهِمْ فَاَقَمْتَ لَهُمُ الصَّلٰوةَ فَلْتَقُمْ طَٓائِفَةٌ مِنْهُمْ مَعَكَ وَلْیَاْخُذُٓوا اَسْلِحَتَهُمْࣞ فَاِذَا سَجَدُوا فَلْیَكُونُوا مِنْ وَرَٓائِكُمْࣕ وَلْتَاْتِ طَٓائِفَةٌ اُخْرٰى لَمْ یُصَلُّوا فَلْیُصَلُّوا مَعَكَ وَلْیَاْخُذُوا حِذْرَهُمْ وَاَسْلِحَتَهُمْۚ وَدَّ الَّذٖینَ كَفَرُوا لَوْ تَغْفُلُونَ عَنْ اَسْلِحَتِكُمْ وَاَمْتِعَتِكُمْ فَیَمٖیلُونَ عَلَیْكُمْ مَیْلَةً وَاحِدَةًؕ وَلَا جُنَاحَ عَلَیْكُمْ اِنْ كَانَ بِكُمْ اَذًى مِنْ مَطَرٍ اَوْ كُنْتُمْ مَرْضٰٓى اَنْ تَضَعُٓوا اَسْلِحَتَكُمْۚ وَخُذُوا حِذْرَكُمْؕ اِنَّ اللّٰهَ اَعَدَّ لِلْكَافِرٖینَ عَذَابًا مُهٖینًا

Translations
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
Saheeh International
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
