When you (O Prophet) are with them, and stand to lead them in prayer, let one party from them stand up (in prayer) with you, taking their arms with them: When they finish their prostration's, let them take their position in the rear. And let the (believers of) other party come up which have not yet prayed— And let them pray with you, taking all precautions, and bearing arms: Those who disbelieve wish, if you were careless of your arms and your baggage, to attack you in a single attack (or rush). But there is no blame on you if you put away your arms because of the inconvenience of rain or because you are ill; But take every precaution for yourselves. Allah has prepared a humiliating punishment for the disbelievers.
