Are jinn obligated to perform Hajj like humans, and do they perform Hajj with humans at the same time, and do they stone Iblis?

The destiny of Jinn is like the destiny of humankind; among them are believers and disbelievers, righteous and wicked. The destiny of the believers is Paradise, and the destiny of the disbelievers is Hellfire, because Allah Almighty created Jinn and humankind for worship, and He sent the Prophet Muhammad, peace be upon him, to all worlds. Scholars have inferred this from Quranic verses.

Jinn are obligated to perform Hajj and other acts of worship. They perform Hajj with humans at the same time. As for the stoning of the Jamarat, it is prescribed in Hajj as an emulation of the Prophet, peace be upon him, and it signifies the symbolic stoning of Satan, not the literal stoning of Iblis.

The obligations of Jinn may differ from those of humankind in some matters due to the difference in their nature.
