Ayah

إِلَّا مَن رَّحِمَ رَبُّكَ ۚ وَلِذَٰلِكَ خَلَقَهُمۡ ۗ وَتَمَّتۡ كَلِمَةُ رَبِّكَ لَأَمۡلَأَنَّ جَهَنَّمَ مِنَ ٱلۡجِنَّةِ وَٱلنَّاسِ أَجۡمَعِينَ
Translation

Except those on whom thy Lord hath bestowed His Mercy: and for this did He create them: and the Word of thy Lord shall be fulfilled: "I will fill Hell with jinns and men all together."<br/>
Tafsir

except those on whom your Lord has mercy, [those] for whom He desires good, and so they do not differ in it - and that is why He created them, that is, [He created] those of difference for that [in other words, so that they should differ] and those deserving mercy for that [in other words, so that they should receive mercy]. And the Word of your Lord has been fulfilled, namely: 'I will surely fill Hell with jinn and mankind together'.
