Al-Infitar (The Cleaving, Bursting Apart)

Sūrat al-Infiṭār (Arabic: سورة الانفطار‎) (The Cleaving, Bursting Apart) is the 82nd sura of the Qur'an 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’. This word, ‘Unfatarat’ is used in this chapter in order to describe the splitting the sky on the day of Judgment. This chapter (Al-Infitar), along with Chapter At-Takwir and Al-Inshiqaq provide exhaustive description about ‘Day of Judgment’.

Cryptomnesia

Cryptomnesia occurs when a forgotten memory returns without its being recognised as such by the subject, who believes it is something new and original. It is a memory bias whereby a person may falsely recall generating a thought, an idea, a song, or a joke,[1] not deliberately engaging in plagiarism but rather experiencing a memory as if it were a new inspiration. Sentences in scientific papers that are identical to sentences from some of the references used to write the paper often stem from cryptomnesia.
