Quran 50:38. We assuredly created the heavens and the earth and all that is between them in six days, and nothing of fatigue touched us.
As I have said on my thread about what the Quran says, the Quran is simply copying the bible when it states the heaven and earth were created in six days.
Both the bible and Quran say one of Gods days is a thousand years, therefore they are both saying heaven and earth were created in six thousand years and they are both wrong. This is clear evidence the Quran is plagiarism from the bible.
Quran, surah 7.54 Lo! your Lord is Allah who created the heavens and the earth in six days.
Quran, surah 10.3 Lo! your Lord is Allah who created the heaven and earth in six days.
Quran, surah 11.7 And He it is. Who created the heavens and the earth in six days.
Quran, surah 25.59 Who created the heaven and earth and all that is between them in six days.
Quran, surah 50.38 And surely We created the heaven and earth, and all that is between them, in six days.
Quran, surah 57.4 He it is Who created the heaven and earth in six days.
Quran, surah 22.47 A day in the sight of the Lord is like a thousand years of your reckoning.
Quran, surah 32.4 Allah it is who created the heaven and earth, and that which is between them, in six days.
Quran, surah 32.5 He directs the ordinance from the heaven unto the earth; then it ascends unto him, in a day whereof the measure is a thousand years of that you reckon.
