The Quran makes it clear about the creation of the universe in 6day:

"To Him is due the primal origin of the heavens and the earth: When He decreeth a matter, He saith to it: "Be," and it is"
Quran 2:117
Your Guardian-Lord is Allah, Who created the heavens and the earth in six days, and is firmly established on the throne (of authority): He draweth the night as a veil o'er the day, each seeking the other in rapid succession: He created the sun, the moon, and the stars, (all) governed by laws under His command. Is it not His to create and to govern? Blessed be Allah, the Cherisher and Sustainer of the worlds!
Quran 7:54
Verily your Lord is Allah, who created the heavens and the earth in six days, and is firmly established on the throne (of authority), regulating and governing all things. No intercessor (can plead with Him) except after His leave (hath been obtained). This is Allah your Lord; Him therefore serve ye: will ye not receive admonition?
Quran 10:3
He it is Who created the heavens and the earth in six Days - and His Throne was over the waters - that He might try you, which of you is best in conduct. But if thou wert to say to them, "Ye shall indeed be raised up after death", the Unbelievers would be sure to say, "This is nothing but obvious sorcery!"
Quran 11:7
He Who created the heavens and the earth and all that is between, in six days, and is firmly established on the Throne (of Authority): Allah Most Gracious: ask thou, then, about Him of any acquainted (with such things).
Quran 25:59
Say: Is it that ye deny Him Who created the earth in two Days? And do ye join equals with Him? He is the Lord of (all) the Worlds.
He set on the (earth), mountains standing firm, high above it, and bestowed blessings on the earth, and measure therein all things to give them nourishment in due proportion, in four Days, in accordance with (the needs of) those who seek (Sustenance). Moreover He comprehended in His design the sky, and it had been (as) smoke: He said to it and to the earth: "Come ye together, willingly or unwillingly." They said: "We do come (together), in willing obedience."

So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge.
Quran 41:9-12

According to al-Muthanna -al-Hajjaj-Hammid -'Ata' b. al-Sa'ib -'Ikrimah: The Jews asked the Prophet: What about Sunday? The Messenger of God replied: On it, God created the earth and spread it out. They asked about Monday, and he replied: On it, He created Adam. They asked about Tuesday, and he replied: On it, He created the mountains, water, and so on. They asked about Wednesday, and he replied: Food. They asked about Thursday, and he replied: He created the heavens. They asked about Friday, and he replied: God created night and day. Then, when they asked about Saturday and mentioned God's rest(ing on it), he exclaimed : God be praised! God then revealed: "We have created the heavens and the earth and what is between them in six days, and fatigue did not touch Us."

Accordig to Tafsir al-Jalalayn, trans. Feras Hamza, Royal Aal al-Bayt Institute for Islamic Thought:
Then He ordained them (the [suffixed] pronoun refers back to al-samā’, ‘the heaven’, because it [al-samā’] actually denotes that plural [sense] to which it will lead [in the following clause), in other words, He made them to be, seven heavens in two days — Thursday and Friday. He completed them in the last hour thereof, in which He created Adam — which is why He does not say sawā’an, ‘evenly’ here [as He did earlier]; what is said here concords with those verse in which it is stated that the heavens and the earth were created in six days; and in each heaven He revealed its commandment’, that to which He commanded those in it [to follow], in the way of obedience and worship. And We adorned the lowest heaven with lamps, with stars, and [this was also] to guard them (hifzan is in the accusative because of its implicit verbal sense, in other words, ‘We guarded it against the devils lest they try to listen therein [to the angels] by stealth with meteors’). That is the ordaining of the Mighty, in His kingdom, the Knower, of His creatures.
Surah 41 Ayah 12

Al Munajjid
So the earth was created in two days, and the mountains were created and the sustenance measured in two more days which makes a total of four, i.e., this took the other two days. Then the creation of the seven heavens took two days. So the total is six days of the Days of Allaah, may He be glorified and exalted.
Were the heavens and the earth created in six days or eight?
