This last book was verified by Abū ʿAbd Allāh al-Ḥaddād in the year 1407 AH, and it was published by Dār al-ʿĀṣimah in Riyadh.

Brockelmann also attributed to Abū Dāwūd a book entitled *al-Tanzīl fī al-Rasm* (1), stating that it exists in the Qarawiyyīn Library in Fez. We have not found anyone who mentioned it or referred to it before him, and it is most likely our opinion that it is among the works of Abū Bakr ibn Abī Dāwūd al-Sijistānī, for it has been mentioned that he had an interest in the Qur'anic sciences (2), and he has a printed book entitled *al-Maṣāḥif*. Perhaps it is the same book, and God knows best.

Brockelmann also claimed that Abū Dāwūd had another book entitled *al-Baʿth wa al-Nushūr* (3), and the same view was adopted by the Academy of Research at the Āl al-Bayt Foundation in its comprehensive indexes of the Arab-Islamic heritage (4), where it was mentioned as attributed to Abū Dāwūd. Likewise, Dr. Taqī al-Dīn al-Nadwī (5) did the same, listing it among the works of Abū Dāwūd. Brockelmann indicated the existence of a manuscript copy of it in Damascus in its Ẓāhiriyyah Library, while the Academy of Research indicated the existence of copies of it in the Azhar Library.

Upon our return to the indexes of the Ẓāhiriyyah manuscripts, which were compiled by our generous colleague Professor Yāsīn al-Sawwās (6), it becomes clear to us that Brockelmann was—
