Masa'il Abdallah ibn Salam

The Masāʾil ʿAbdallāh ibn Salām ('Questions of ʿAbdallāh ibn Salām'), also known as the Book of One Thousand Questions among other titles, is an Arabic treatise on Islam in the form of Muḥammad's answers to questions posed by the Jewish inquirer ʿAbdallāh ibn Salām. The work is considered apocryphal, with neither the questions nor the answers attributable to the named protagonists.

Originally composed in the tenth century and widely translated, the Masāʾil is today regarded as a piece of world literature. A Latin version appeared in the twelfth century and a Persian one by the sixteenth. From Latin it was translated into Dutch, French, German, Italian and Portuguese; from Persian into Urdu, Malay and Tamil. From the Arabic, translations were also made into Buginese, Javanese, Sundanese and English.
