they (would have) remained
Thou wast not on the Western side when We decreed the Commission to Moses, nor wast thou a witness (of those events).
Then, when We decreed (Solomon's) death, nothing showed them his death except a little worm of the earth, which kept (slowly) gnawing away at his staff: so when he fell down, the Jinns saw plainly that if they had known the unseen, they would not have tarried in the humiliating Penalty (of their Task).
当我以我的命令启示穆萨的时候,你没有在西山边,也没有亲眼看见。
我决定他死亡的时候,只有持他的手杖的柱虫,指示他们他已经死了。当他倒下的时候,精灵们恍然大悟:假若他们能知幽玄,那末,他们未曾逗留在凌辱的刑罚中。
