Al-Būsīrī (Arabic: ابو عبد الله محمد بن سعيد بن حماد الصنهاجي البوصيري, romanized: Abū ʿAbdallāh Muhammad ibn Saʿīd al-Shanhājī al-Būṣīrī; 1211–1294) was a Sanhaji Berber Muslim poet belonging to the Shadhiliyya order, being direct disciple of Sheikh Abul Abbas al-Mursi. His magnum opus, the Qaṣīda al-Burda (Poem of the Mantle), in praise of the Prophet Muhammad, is one of the most popular poems in the world.
Al-Busiri was born Muhammad b. Saʿīd b. Ḥammād b. Muḥsin b. Abū Surūr b. Ḥibbān b. ʿAbdullah b. Mallak al-Sanhajī. Al-Maqrizi mentions that his family hailed from the Hammad citadel in Morocco and that they were of the Banu Habnun tribe. He lived in Egypt, where he wrote under the patronage of Ibn Hinna, the vizier.
In his Qaṣīda al-Burda, he claims that Muhammad cured him of paralysis by appearing to him in a dream and wrapping him in a mantle. The poem has had a unique history (cf. I. Goldziher in Revue de l'histoire des religions, vol. xxxi. pp. 304 ff.). Even in the poet's lifetime it was regarded as sacred. Up to the present time its verses are used as amulets; it is employed in the lamentations for the dead; it has been frequently ed and made the basis for other poems, and new poems have been made by interpolating four or six lines after each line of the original. It has been published with English translation by Faizullabhai (Bombay, 1893), with French translation by René Basset (Paris, 1894), with German translation by C. A. Ralfs (Vienna, 1860), and in other languages elsewhere.
