al-Qurtubi begins his tafsir of surah al-Zumar [39] - also sometimes referred to as surah al-Ghuraf - by writing:
[قال وهب بن منبه : من أحب أن يعرف قضاء الله - عز وجل - في خلقه فليقرأ سورة الغرف ]
Wahb ibn Munabbih said: Whoever would like to know about Allah's final judgement of His creation should read surah al-Ghuraf.
[Jaami' li-Ahkam al-Qur'an 15/207]
Translator's note: This theme of the surah is especially clear in its latter part in which Allah vividly describes events of the Day of Resurrection.
