Smoke After Big Bang In Quran

After the Big bang Big Bang and Expanding Universe In Quran there was only hot smoke and the universe was cooling down, until the matters formed. Speaking of the origin and nature of this universe, everybody knows that it was nothing but a mass of smoke and gaseous at the beginning. This certainly is mentioned in Quran

“He placed firmly embedded mountains on it, towering over it, and blessed it and measured out its nourishment in it, laid out for those who seek it-all in four days. Then He turned to heaven when it was smoke and said to it and to the earth, “Come willingly or unwillingly.” They both said, “We come willingly.” (Qur’an, 41:10-11)

Here Quran clearly states that after the event of great explosion and during the formation of Universe everything was nothing but smoke, Further it also talk about two energy (Earth’s Gravitational Force) and Heaven (Dark energy) to come willingly to form the Earth our planet. This was also noted in Tafsir by Ibn Khatir

Quote from Ibn Khaitr Tafsir

“(and said to it and to the earth: “Come both of you willingly or unwillingly.”) meaning, `respond to My command and be subjected to this action, willingly or unwillingly.’
(They both said: “We come willingly.”) meaning, `we will respond to You willingly and everything that You want to create in us — angels, Jinn and men — will all be obedient to You.”

So how could an illiterate man 1400 years ago came to know of Universe being just a hot smoke.?

“Nay, but they, the clear Ayat [i.e the description and the qualities of Prophet Muhammad SAW written like verses in the Taurat (Torah) and the Injeel (Gospel)] are preserved in the breasts of those who have been given knowledge (from the people of the Scriptures). And none but the Zalimun (polytheists and wrongdoers, etc.) deny Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.).” [Quran 29:49]
