“This book belongs in every library that presently includes Khargūshī, Sulamī, Hujvīrī, and Qushayrī.” - Christopher Melchert, in: Journal of Islamic Studies 24.2 (2013), 204-206. [doi:10.1093/jis/ett004]"The book, which is an important Sufi manual, is highly recommended for scholars and students in the field of Islamic studies, Middle Eastern Studies, Islamic thought, Iranian studies and Sufism. It is a valuable addition to the field." - Eliza Tasbihi, in: The Muslim World Book Review 33.4 (2013)“This meticulously executed critical edition of the Sufi treatise by an early Sufi master Abū l-Ḥasan al-Sīrjānī (d. ca. 470/1077), who hailed from the Iranian province of Kirmān, is a welcome addition to the body of early Sufi literature that has been growing steadily over the past few years. […] Such a selfless dedication on the part of a scholar to making new Sufi texts available to his peers is highly commendable, to say the least. A mere look at the detailed and variegated indices appended to the critical text of Kitāb al-Bayāḍ wa-l-sawād and to Orfali’s other editions of Sufi works reveals the painstaking care and dedication that he and his co-editors have invested in their preparation.” - Alexander Knysh, in: Journal of Sufi Studies 3 (2014)“Orfali and Saab are to be commended for their careful and nearly flawless Arabic text edition (pp. 1–411), which is followed by a series of useful indices citing the appropriate paragraphs for Qur’anic quotations (pp. 413–24), hadith traditions (pp. 425–34), place names (pp. 435–36), individuals mentioned in the text (pp. 438–63), verses quoted in the text (pp. 465–74), and, finally, Sufi technical terms (pp. 475–506).” - Th. Emil Homerin, in: Journal of Near Eastern Studies 73.2 (2014), pp. 370-371. [DOI: 10.1086/677269]“…the Orfali and Saab edition of Black and White is meticulously edited, and comes with a well-researched 50-page introduction which discusses Sirjani’s life, his style of writing, the role of the hikam in his work, the structure of the work, his sources, as well as the manuscripts that were used.” - Atif Khalili, in: Studies in Religion / Sciences Religieuses Vol. 45, 1 (2016), p. 79-80"The editors must be thanked for having put at our disposal this important source for the history of Islamic mysticism." - Francesco Chiabotti, in: Al-Abhath 64 (2016)
