Būstān al-jāmiʿ li-jamīʿ tawārīkh al-zamān (Arabic: بستان الجامع لجميع تواريخ الزمان, lit.
'General Garden of All the Histories of the Ages')[1] is an anonymous Arabic chronicle from Ayyubid Syria.
The scribe attributes it to a qāḍī named ʿImād al-Dīn al-Iṣfahānī, but if this is not a mistake it must be a different person from ʿImād al-Dīn al-Iṣfahānī, author of al-Barq al-Shāmī, whose information on the reign of Saladin is less extensive than that found in the Būstān and sometimes contradicts it.
[1] It focuses on Aleppo and Egypt, but contains information not found in any earlier source.
It does share a lost source with Ibn Abī Ṭayyiʾ and cites al-ʿAẓīmī.
