The Quran

وَلَو شِئنا لَآتَينا كُلَّ نَفسٍ هُداها وَلٰكِن حَقَّ القَولُ مِنّي لَأَملَأَنَّ جَهَنَّمَ مِنَ الجِنَّةِ وَالنّاسِ أَجمَعينَ

Muhammad Asad

Yet had We so willed, We could indeed have imposed Our guidance upon every human being:¹ but[We have not willed it thus - and so] that word of Mine has come true: "Most certainly will I fill hell with invisible beings as well as with humans, all together!"²

Lit., "We could indeed have given unto every human being (nafs) his guidance", i.e., forcibly: but since this would have deprived man of his ability to choose between right and wrong - and, thus, of all moral responsibility - God does not "impose" His guidance upon anyone (cf. 26:4 and the corresponding note).
See 7 :18 as well as the last paragraph of 11: 119. As regards the "invisible beings" (jinn), see Appendix III.
