Shakh ‘Abdul ‘Azīz b. Bāz (rahimahullah) was asked:
“Is there a specific place for the burial of ‘Easa (alayhis salām)?”
This has been reported in some narrations, but there are observations regarding the authenticity that he will be buried in the prophetic garden (rawdah).
I do not know of anything established. This (burial place) has been mentioned by ibn Kathīr (rahimahullah) and others, however I am unaware of a connected chain (of narration) that he will be buried in the prophetic garden. (Therefore) this (saying) is not to be depended on, and Allah knows best.
