Quran says about the judgemnt day

Muslims believe that the Qur'an provides the framework for understanding the Day of Judgment. Ideas such as the return of Jesus to Earth and the second kingdom before the occurrence are believed to be indirectly mentioned in the Qur'an.
There are a wide variety of views and interpretations of the verses in the Qur'an referring to the Day of Judgment.

• The timing of the day of judgment is not known to people - only God knows when it will occur.^[10]
• Muhammad, as the messenger of Islam, does not know when the day will be.^[11][12]
• Muhammad cannot bring it forward.^[13]
• The people will believe that a short time has passed between their deaths and resurrection.^[14]
• Nothing will remain except God.^[15]
• God will resurrect people even if they turn to stone or iron.^[16]
• The majority of Islamic scholars^[who?] are of the view that the Trumpet will be blown twice: the first time all creatures will swoon and the second time the resurrection will come to pass. This is based on the verse of Qur'an in which God says (interpretation of the meaning):

The Trumpet will (just) be sounded, when all that are in the heavens and on earth will swoon, except such as it will please Allah (to exempt). Then will a second one be sounded, when, behold, they will be standing and looking on!

—Sura 39 (Az-Zumar), ayah 68^[17]

• The Qur'an declares that the belief in God and the belief in the last prophet Muhammad (including the belief in all the prophets of Islam) and the last Day of Judgment and the doing of good works on earth is the requirement for salvation, provided that Shirk is not committed. Believing in and observing in the five pillars of Islam: tawheed, salat, fasting, Zakat and Hajj are necessary to secure heaven. ^[18]

• No injustice shall be done

Surely God does not do injustice to the weight of an atom, and if it is a good deed He multiplies it and gives from Himself a great reward.

—Qur'an, sura 4 An-Nisa, ayah 40.
