Several biographical notices on the seventeenth-century Egyptian chronicler Shams al-Dīn Muḥammad b. Muḥammad Abi ‘l-Surūr b. Muḥammad b. ‘Alī al-Bakrī al-Ṣiddīqī al-Miṣrī al-Shāfi’ī al-Wārthī al-Ash’arī sibṭ Abi ‘l-Ḥasan, better known as Ibn Abi ‘l-Surūr, have been written in more than one language, but most of them contain misleading, and sometimes erroneous, statements about his birth and death dates and works. The new edition of the Encyclopaedia of Islam, for instance, in its brief notice ‘al-Bakrī, b. Abi ‘l-Surūr’, states that this is the ‘name of two Arab historians of the notable family of Egyptian shaykhs of the Bakriyya ṭarīḳa’, viz. (1) Muḥammad b. Abi ‘l-Surūr b. Muḥammad b. ‘Alī al-Ṣiddīḳī al-Miṣrī, d. 1028/1619; (2) Muḥammad b. Muḥammad b. Abi ‘l-Surūr Shams al-Dīn Abū ‘Abdallāh, son of the above, b. c. 1005/1596, d. c. 1060/1650. While the entry ‘ al-Bakrī b. Abi ‘l-Surūr’ really refers to the first, it does not, as such, apply to the alleged second historian whose identity, supposed works, and relationship to the first have to be established. The notice, moreover, gives wrong dates and erroneously ascribes some of the works of Ibn Abi ‘l-Surūr to his supposed son.
