Abu âÂÂl-Ḥusayn IsḥÃÂq ibn IbrÃÂhëm ibn SulaymÃÂn ibn Wahb al-KÃÂtib () (flourished in the second half of the tenth century CE, d. after 946âÂÂ947), commonly known as Ibn Wahb al-KÃÂtib, is noted as the author of the rhetorical treatise KitÃÂb al-BurhÃÂn fë wujà «h al-bayÃÂn (ÃÂÃÂêÃÂçè çÃÂèÃÂñÃÂÃÂçàÃÂÃÂàÃÂÃÂìÃÂÃÂÃÂàçÃÂèÃÂÃÂÃÂçÃÂ) â The Book of the Demonstration of the Aspects of BayÃÂn.
Ibn Wahb al-KÃÂtib came from a distinguished family of scribes and secretaries. His grandfather SulaymÃÂn had been a minister to al-Muhtadë and al-Muÿtamid, but had been imprisoned during the reign of al-Muwaffaq, dying in prison in 905. Little is known of ibn Wahb's own life, but his KitÃÂb al-BurhÃÂn fë wujà «h al-bayÃÂn was composed after the death of ÿAlë ibn ÿêsàibn dÃÂÃ¾à «d ibn al-jarrÃÂḥ (1 August 946).
According to his surviving writing, ibn Wahb was author of works entitled KitÃÂb al-Ḥujja, KitÃÂb al-êá¸ÂÃÂḥ, KitÃÂb al-Taÿabbud and KitÃÂb AsrÃÂr al-ḲurþÃÂn. It appears that these are lost (and not mentioned by other sources). However, ibn Wahb's KitÃÂb al-BurhÃÂn fë wujà «h al-bayÃÂn, also known as Naqd al-nathr (, Book on Prose Criticism), survives; it is a study of Arabic style, rhetoric, and the art of the secretary composed from a Shëÿë perspective, and attempts to deploy Greek, Muÿtazilë and ImÃÂmë ideas in examining Arabic writing. This work was in the early twentieth century misattributed to ibn Wahb's contemporary Qudama ibn Ja'far, until a more complete manuscript was discovered in the Chester Beatty Collection by ÿAlë Ḥasan ÿAbd al-QÃÂdir, showing the correct attribution.
