Saveh

Saveh (Sava), in north-central Iran between Tehran and Hamadan, was a medieval town famous for its library, destroyed in the Mongol invasions of the early 13th century. The Shafi'i Qur'an commentator al-Wahidi (d. 1076), author of the Asbab al-Nuzul (Occasions of Revelation) and several tafsirs, came from a family that originated in Saveh, though he himself was born and worked in Nishapur.
