فَكَانَ عَٰقِبَتَهُمَآ أَنَّهُمَا فِي ٱلنَّارِ خَٰلِدَيۡنِ فِيهَاۚ وَذَٰلِكَ جَزَٰٓؤُاْ ٱلظَّٰلِمِينَ ١٧
So the outcome for both of them is that they will be in the Fire, abiding eternally therein. And that is the recompense of the wrongdoers.
Translation: Saheeh International (English)
Each word's meaning and sound
So the ultimate outcome of Satan and whoever followed him will be that they (meaning the followed Satan and the human followers of his) will be in the hellfire on the Day of Judgement, wherein they shall have to remain forever. That requital that awaits them is the requital of those who oppress themselves by trespassing the limits of Allah.
