Problem: The verses describe the creation order of the Earth and heavens in the same order as Genesis, which has the Earth + vegetation (sustenance) created before the heavens - all of which is scientifically incorrect.
Original text:
9: Disbelieve ye verily in Him Who created the earth in two Days, and ascribe ye unto Him rivals? He is the Lord of the Worlds.
10: He placed therein firm hills rising above it, and blessed it and measured therein its sustenance in four Days, alike for (all) who ask;
11: Then turned He to the heaven when it was smoke, and said unto it and unto the earth: Come both of you, willingly or loth. They said: We come, obedient.
12: Then He ordained them seven heavens in two Days and inspired in each heaven its mandate; and We decked the nether heaven with lamps, and rendered it inviolable. That is the measuring of the Mighty, the Knower.
Solution:
Rearrange the order of the verses so that the story reads in the correct order.
Remove the statement which says that the Earth existed whilst the heavens were still smoke.
Remove any references to the amount of time taken.
