8 Preface يَومَ تَكونُ السَّماءُ كَالمُهلِYusuf AliThe Day that the sky will be like molten brass,1Cf. 18:29 (where the wrongdoer will have a drink like melted brass in Hell); and 44:45, (where his food will be like molten brass). Here the appearance of the sky is compared to molten brass, or, as some understand it, like the dregs of oil. What is conveyed by the metaphor is that the beautiful blue sky will melt away.
