When thou ( O Messenger ) 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 .
