Kraemer in his translation of al-Tabari notes on page 223: "'Ayni comments, citing al-Sibt (b. al-Jawzi), that Tabari's statement here is surprising since the tombs of the Abbasid caliphs are in fact known, e.g., the tomb of al-Saffah is in Anbar beneath the minbar; and those of al-Mahdi in Masabadhan, Harun in Tus, al-Ma'mun in Tarsis, and al-Mu'tasim, al-Wathiq and al-Mu'tawakkil in Samarra."
