Then He turned to the heavens when it was smoke

God said in The Holy Quran:

ثُمَّ اسْتَوَىٰ إِلَى السَّمَاءِ وَهِيَ دُخَانٌ فَقَالَ لَهَا وَلِلْأَرْضِ ائْتِيَا طَوْعًا أَوْ كَرْهًا قَالَتَا أَتَيْنَا طَائِعِين

(Then He turned to the heavens when it was smoke)...[Holy Quran 41:11]

 The first thing by "heaven" is meant the whole universe, as becomes obvious from the following sentences. In other words, "turning to the heaven" means that Allah turned to the creation of the universe. second, by "smoke" is implied the initial and primary stage of matter, in which it lay diffused in space in a shapeless, dust like condition before the formation of the universe.The modern Scientists describe the same thing as nebulae, and the same also is their view about the beginning of the universe.That is, before creation the matter of which the universe was built lay diffused in smoke-like nebulous form.

In  modern science the study of the origin. observational and theoretical, clearly indicates that, at one point in time, the whole universe was nothing but a cloud of 'smoke' (i.e. an opaque highly dense and hot gaseous composition). This is one of the undisputed principles of standard modern cosmology. Scientists now can observe new stars forming out of the remnants of that 'smoke'. The illuminating stars we see at night were, just as was the whole universe, in that 'smoke'(SubhanAllah)
