أَلْقِيَا فِي جَهَنَّمَ كُلَّ كَفَّارٍ‌ عَنِيدٍ (Cast, both of you [ 0 angels,] into Jahannam every stubborn disbeliever.... 50:24]. The verb alqiya is grammatically dual in number, that is, addressed to two persons. It appears that Allah will say these words to the Sa'iq and Shahid angels; Allah will order them to throw him in the fire of Hell. Some other scholars explain it differently (Ibn Kathir).
