All praise is due to Allah, and may peace and blessings be upon the Messenger of Allah.
The jinn are obligated to worship Allah, the Most High, and are addressed by the message of the Prophet ﷺ. They will receive reward or punishment, just as Allah says:
﴿And I did not create the jinn and mankind except to worship Me.﴾ [Adh-Dhariyat: 56].
The stronger opinion is that believing jinn will enter Paradise and enjoy its blessings, just as human believers do. This is supported by the statement of Allah:
﴿But for whoever fears standing before his Lord there will be two gardens. So which of the favors of your Lord would you deny?﴾ [Ar-Rahman: 46–47].
The address in this verse is directed to both jinn and humankind, indicating that both are included in the general promise of Paradise and its blessings.
Allah also says, describing the Hūr al-ʿAyn:
﴿Untouched before them by any human or jinn.﴾ [Ar-Rahman: 56].
Some scholars have used this verse as evidence that believing jinn will receive blessings in Paradise appropriate to them, just as human beings receive their blessings.
However, there is no explicit text specifying whether the jinn will have Hūr al-ʿAyn exclusively for themselves or whether they will share one type of Hūr al-ʿAyn with human beings. These are matters of the unseen, and it is not permissible to make definitive claims about their details without evidence.
Conclusion: Believing jinn are promised Paradise and its blessings. However, the exact nature of their enjoyment, and whether they will have Hūr al-ʿAyn of their own or share them with human beings, has not been clarified by any explicit text. It is therefore better not to delve into matters for which there is no evidence.
And Allah knows best.
