Hadith.2821 - Ishaq ibn Ammar asked Imam Abu Ibrahim عليه السلام about a severely ill person who is unable to perform circumambulation around the Kaaba.
The Imam عليه السلام replied: "No, but he should be carried and circumambulated with."
It is also narrated from Hariz that there is leniency allowing circumambulation and stoning of the Jamara to be performed on behalf of a person who is unconscious or incapable.
