A commentary on Sirāj al-Dīn al-Sajāwandī's Kitāb al-Farāʼiḍ.

The text is very well annotated. Of particular interest are Jones's notations about his reading, e.g. f74r "28th August 1792, Crishna-Nagar" which tell us when and where he read the text.

William Jones wrote a title page (signed 'WJ') on f1r: "Al-Shaīfiyyah: or, A Commentary on the Sirājiyyah, by Sayyad Sharīf. Three times read attentively W.J.". Previously, he had written "twice" read but this is crossed out.

Also on the title page (f1r) we find a note, "Indigofera (Linn. it sh.d be) / Indica (since Indicum was the ancient name of Indigo) / Nīla : since Indicum was the anct. name of Indigo" followed by the note "Property established by Muhammad. So Kurān, see Lacid & milc".

Jones also wrote marginal notes to show Qurʾānic quotations.

He wrote many explanatory notes for himself, both in Arabic and English (e.g. on land as property ff9r-10v, which includes transliterations of relevant sections).

Throughout the text, there are marginal equations made by Jones to explain/exemplify the formulae described by al-Jurjānīin the MS.

He sometimes translates whole sections of the text, e.g. on freedom in f41v.

There are some annotations which show how Jones understands the text as it applies to his surroundings, e.g. f45v in which he notes "hence, حرام زان".

On f164v, he draws a line underneath the explicit before the colophon and notes "30 Aug 1792: Finished the third careful reading of this book."

Translation of the colophon: "This pleasant book, called al-Faraʾiḍ al-sharīfiyyah fī sharḥ al-sirājiyyahand writted by al-Sayyid al-Sharīf al-Jurjānī, was completed with the help of al-Malik al-Wahhāb [=Allah, The King who Bestows]. Its great riches were rendered by the hands of His most humble servant, Ḥajj ʿAbd Allāh al-Makkīin the employ and at the request of Sir William Jones who is one of the High Chief Judges in the district of Kolkata. Monday, 28th Dhū ʼl-Qaʿdah 1205AH."

On f165v, he has transcribed (unsigned) the following from Pietro della Valle's Lettere da Basra: "Vidi nella piazza un asino salvatico overo Onagro, piccolo, che in casa del Bascià per galanteria si nudriva: era di forma come tutti gli altri asini, ma di color più chiaro: e dalla testa alla coda nel fila della schiene gli correva una riga di peli bionde, come d'un caval falbo carica di colore ed in correre ed in saltare si vedeva esser molto più leggiero degli asini domestici".
