It says the earth was created in two days. And later on in the next verse it says four days?
Keep in mind the total duration of heavens and earth creation is six days. So did the earth take up 2 days out of six. or four days?
Specifically what is the meaning of the verse below about the four days.
“Say (O Muhammad): Do you verily disbelieve in Him Who created the earth in two Days? And you set up rivals (in worship) with Him? That is the Lord of the ‘Aalameen (mankind, jinn and all that exists).
He placed therein (i.e. the earth) firm mountains from above it, and He blessed it, and measured therein its sustenance (for its dwellers) in four Days equal (i.e. all these four ‘days’ were equal in the length of time) for all those who ask (about its creation).
Then He rose over (Istawa) towards the heaven when it was smoke, and said to it and to the earth: ‘Come both of you willingly or unwillingly.’ They both said: ‘We come willingly.’
Then He completed and finished from their creation (as) seven heavens in two Days and He made in each heaven its affair. And We adorned the nearest (lowest) heaven with lamps (stars) to be an adornment as well as to guard (from the devils by using them as missiles against the devils). Such is the Decree of Him, the All-Mighty, the All-Knower”
