This is a scholarly commentary by the renowned 3rd-century AH philologist, Abi Sa'id al-Sukkari, on the collected poems (Diwan) of Ka'b ibn Zuhayr, a famous companion of the Prophet Muhammad. The work meticulously explains the linguistic, grammatical, and historical context of Ka'b's poetry, most notably his famous ode "Banat Su'ad" (The Poem of the Mantle). Al-Sukkari's analysis provides invaluable insights into the classical Arabic language and pre-Islamic poetic traditions, making it an essential resource for students and researchers of Arabic literature and history.
