The Cleaving in Sunder [1] (Arabic: الانفطار, al-infiṭār, also known as "The Cleaving" and "Bursting Apart") is the 82nd sura of the Quran, with 19 ayat.

The chapter is named 'Al-Infitar' because of the occurrence of the word 'unfatarat' in the first verse of this chapter.

Infitar means 'split asunder': the word 'Unfatarat' is used in this chapter in order to describe the splitting of the sky on the day of Judgment.

This chapter (Al-Infitar), along with chapters At-Takwir and Al-Inshiqaq, provides an exhaustive description about the 'Day of Judgment'.
