Is there a text that mentions that prayer in Al-Aqsa Mosque is equivalent to five hundred prayers? And are there other hadiths besides what you mentioned in Al-Bazzar and Al-Tabarani?

The narrations regarding the virtue of prayer in Al-Aqsa Mosque vary. Some state it is equivalent to 500 prayers, others to 250, some to 1,000 prayers (which Al-Iraqi preferred), some to 50,000 prayers, and others to 100 prayers. The questioner's assertion that Al-Tabarani's dictionaries and Al-Bazzar's Musnad are among the rare or strange (unusual) works is unfounded, as they are reliable books, and what matters is the chain of narration (isnad (definition)).
