Sūrat al-Burūj (, "The Great Star") is the eighty-fifth chapter ( sura) of the Quran with 22 verses.
The word "Al-Burooj" in the first verse is translated to stars, mainly 'great stars'. The Surah opens with an oath by a heaven full of stars: By the sky containing great stars. The Arabic word Al-Burooj is interpreted in several ways. The word Al-Burooj is the plural of Burj which means fort or tower; something that can be seen from a distance. Ibn ‘Abbas, Mujahid, Ad-Dahhaj, Al-Hasan, Qatadah and As-Suddi said Burj means stars. Ibn Jareer chose the view that it means the positions of the sun and the moon, which are twelve Burooj. The sun travels through each one of these Burj in one month. The moon travels through each one of these Burj in two-and-a-third days, which makes a total of twenty-eight positions, and it is hidden for two nights [making a month of 30 approximately].
Interpreters give several different versions of the story to be referred to in verses 4-8: persecution of Christians by Dhu Nuwas in Yemen, persecutions by Nebuchadnezzar, and people of the trench. It has been documented that Dun Nuwas burned 20,000 Christians alive in a burning trench because they refused to convert to Judaism. Quranic exegetes produced different interpretations of the term 'preserved tablet' in verse 22. In this surah the relationship of Quran to the 'Preserved Tablet' is correlated with the relation of the stars 'Al-Buruj' to the heavens 'Al-Sama'. Mu'tazilites argued that revelations were created initially in the preserved tablet. This seems to be close to another term, 'Mother of all books' (umm al-kitab), mentioned in 13:39 and 43:4.
