102. When you, O Messenger, are with them in the army, fighting the enemy, and you wish to lead them in prayer, then divide the army into two groups: one group should stand and pray with you, keeping their weapons with them during the prayer, whilst the other group guards you. When the first group has completed one unit of prayer with the Imam, it must complete the rest of the prayer on its own, and then go to the back to face the direction of the enemy. Then the other group, which was on guard and which has not prayed as yet, should come and pray one unit of prayer with the leader. When the leader completes the prayer with the salām, they should complete the balance of their prayer on their own. They should be careful of the enemy and keep their weapons with them. The disbelievers wish that you become unmindful of your weapons and your goods when you are in prayer, so that they can attack you in a single assault. There is no sin on you to put down your weapons when you are in difficulty because of rain, illness, and the like. but be careful of the enemy as much as possible. Allah has prepared for the disbelievers a punishment that will humiliate them.
