What is "al-maarij"

Sūrat al-Maʻārij (, “The Ascending Stairways”) is the seventieth sura of the Qur'an with 44 ayat. The Surah takes its name from the word dhil Ma'arij in 3rd ayah. The word appears twice in the Quran. Abdullah Yusuf Ali an Indian Islamic scholar introduces the surah as “This is another Islamic eschatology Surah closely connected in subject matter with the last one. Patience and the mystery of Time will show the ways that climb the Heaven. Sin and Goodness must each eventually come to its own.”
