so that you bring to them
surely He (would) have gathered them
If their spurning is hard on thy mind, yet if thou wert able to seek a tunnel in the ground or a ladder to the skies and bring them a sign,- (what good?). If it were Allah's will, He could gather them together unto true guidance: so be not thou amongst those who are swayed by ignorance (and impatience)!
如果他们的拒绝使你难堪,那末,如果你能找著一条入地的隧道,或一架登天的梯子,从而昭示他们一种迹象,(你就这样做吧。)假若真主意欲,他必将他们集合在正道上,故你绝不要做无知的人。
