When you ˹O Prophet˺ are ˹campaigning˺ with them and you lead them in prayer, let one group of them pray with you—while armed. When they prostrate themselves, let the other group stand guard behind them. Then the group that has not yet prayed will then join you in prayer—and let them be vigilant and armed.1 The disbelievers would wish to see you neglect your weapons and belongings, so they could launch a sweeping assault on you. But there is no blame if you lay aside your weapons when overcome by heavy rain or illness—but take precaution. Indeed, Allah has prepared a humiliating punishment for the disbelievers.
