"And what can make you know what the Day of Judgment is?" The interpretation of al-Ḥasan: meaning, you did not know what the Day of Judgment was until I informed you (L 383).
﴿وَمَا أَدْرَاكَ مَا يَوْمُ الْفَصْلِ﴾ تَفْسِيرُ الْحَسَنِ: أَيْ: أَنَّكَ لَمْ تَكُنْ تَدْرِي مَا يَوْمُ الْفَصْلِ حَتَّى أعلمتك (ل ٣٨٣)
