Answered by: the Eminent Shaykh,ʿAbd al-ʿAzīz ibn Bāz.

[Q]: The questioner asks concerning the language of the jinn, O Eminent Shaykh?

[A]: That which is apparent is that they are like humans, in that they have various languages. Amongst them there are the English (jinn), amongst them there is the French, amongst them there is the American, and amongst them, there is the non-Arab and the Arab; (there are various) races. Because Allāh has said concerning them:

وَأَنَّا مِنَّا الصَّالِحُونَ وَمِنَّا دُونَ ذَٰلِكَ ۖ كُنَّا طَرَائِقَ قِدَدًا ‎

“There are among us some that are righteous and some that are contrary; we are groups having different ways.”
[Jinn, 72:11]

And they are upon different sects. He, Glorified be He, has said:

وَأَنَّا مِنَّا الْمُسْلِمُونَ وَمِنَّا الْقَاسِطُونَ

“And some of us are Muslims and some of us are Qāsitūn (disbelievers).”
[Jinn, 72:14]

So they are of different groups and sects. Amongst them, there is the pure and amongst them, there is the impure. Amongst them, there is the Jahmī (follower of the teachings of the Jahmiyyah), amongst them there is the Sunnī (follower of the Sunnah), amongst them there is the Rāfidhī (from the extreme Shīʿah), amongst them there is the Christian, amongst them there is the Jew and amongst them, there is other than that. (They are of) various groups and sects:

وَأَنَّا مِنَّا الصَّالِحُونَ وَمِنَّا دُونَ ذَٰلِكَ ۖ كُنَّا طَرَائِقَ قِدَدًا ‎

“There are among us some that are righteous and some that are contrary; we are groups having different ways.”
[Jinn, 72:11]

His statement: “…some that are contrary…” is general including (all) other groups.
