Sūrat al-Tīn has eight verses and is believed to have been revealed in Mecca. Chronologically, it is regarded to be the twenty-eighth chapter of the Quran, revealed after Sūrat al-Burūj (85). Its name is taken from the first word of its first verse.
The chapter introduces itself with four divine oaths (verses 1-3) that set the stage for the verses that follow. The oaths invoke the mysteries of the creation of the fig and the olive, and the holiness of Mount Sinai and the city of Mecca. It then discusses how God has created human beings in the best of forms (verse 4). It then mentions the other side of the spectrum which is the lowest level human beings can fall into (verse 5). Those who have faith and do good are exempt from falling to this lowest level, and for them there will be everlasting rewards (verse 6). Finally, the chapter ends by asking a rhetorical question about those who deny retribution and asserts that God is the fairest of all judges (verses 7-8).
