This copy is of excellent textual accuracy, clear script, and utmost precision; errors in it are rare. In its margins are corrections and references to other copies, indicating that it was collated more than once and compared with meticulous care.

A group of scholars has successively studied it; it was read before them, and their names were recorded throughout its pages, which attests to the preciousness of this copy. We have already learned that it was transcribed from the copy of al-Muʾtaman al-Sājī al-Ḥāfiẓ, whose biography has been given earlier. He was a peer of Abū al-Fatḥ al-Karūkhī in audition (samāʿ), and was known for accuracy, reliability, and memorization, as we have explained when discussing al-Karūkhī's copy in his own hand.

The scribe of this copy is Abū Jaʿfar Muḥammad ibn Muḥammad ibn Naṣr ibn Muḥammad ibn Abī al-Qāsim al-Aṣbahānī, known as al-Ṣayrafī. He heard this copy of his upon Abū al-Fatḥ al-Karūkhī, and its chain of transmission appears at the beginning of the first folio of the first volume, for he said: "We were informed by the noble, righteous, ascetic, trustworthy Imām Abū al-Fatḥ ʿAbd al-Malik ibn Abī al-Qāsim ibn Abī Sahl al-Harawī al-Karūkhī, in a ribāṭ… in the months of the year five hundred and forty-five, read before him while I was listening…" His name is also mentioned in another audition upon al-Karūkhī in the year six hundred and thirty-nine, as appears at the end of the last folio of the first volume.

The owner of this copy is Taqī al-Dīn Abū ʿAbd Allāh Muḥammad ibn Aḥmad ibn Muḥammad al-Aṣfahānī, as explicitly stated on the first panel, from the title page, who heard the book upon Abū Naṣr Muḥammad ibn Hibat Allāh ibn
