وَمَا أَدْرَاكَ مَا هِيَهْ نَارٌ حَامِيَةٌ
And what will make you know what it is? A blazing fire. (101:10–11)
Mā adrāka returns, but its target shifts from the surah’s initial designation to the destiny called hāwiyah. The final h in hiyah is commonly analyzed as hāʾ al-sakt, associated with pausal pronunciation.
Nārun ḥāmiyah is a short noun-and-adjective formulation that answers the preceding question. The rhetoric here relies on the power of an economical clarification after carefully heightened anticipation.
