so (that) they (can) assault
Quite a number of the People of the Book wish they could Turn you (people) back to infidelity after ye have believed, from selfish envy, after the Truth hath become Manifest unto them: But forgive and overlook, Till Allah accomplish His purpose; for Allah Hath power over all things.
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. But there is no blame on you if ye put away your arms because of the inconvenience of rain or because ye are ill; but take (every) precaution for yourselves. For the Unbelievers Allah hath prepared a humiliating punishment.
信奉天经的人当中,有许多人惟愿使你们在继信道之後变成不信道者,这是因为他们在真理既明之後嫉视你们的缘故。但你们应当恕饶他们,原谅他们,直到真主发布命令。真主对於万事确是全能的。
当你在他们之间,而你欲带领他们礼拜的时候,教他们中的一队人同你立正,并教他们携带武器。当他们礼拜的时候,叫另一队人防守在你们后面;然后,教还没有礼拜的那一队人来同你礼拜,教他们也要谨慎戒备,并携带武器。不信道的人,希望你们忽视你们的武器和物资,而乘机袭击你们。如果你们为雨水或疾病而感觉烦难,那末,放下武器对于你们是无罪的。你们当谨慎戒备。真主确已为不信道的人而预备凌辱的刑罚。
