Аннотация:The existence of an Arabic MS known as Kitāb al-barakafi 'l-sukūn walharaka wa-hiya 'l-marsuma bi-'ida‘ al-nusū kh man a kh a dh tu ‘anhu min sh uyū kh was known to Delafosse who believed it to be the work of a paternal uncle of Sultan Bello. A. Brass has deduced from internal evidence in the Tazyīn al-waraqāt of ‘Abdullāh ibn Fodio that the work belongs to ‘Abdullāh, and has accepted the title in the form given by Delafosse. Georges Vajda has shown that this title arises from the confusion of two different works, and that the title of ‘Abdullāh's work is ' Idā‘ al-nusū kh man a kh a dh tu ‘anhu min al- sh uyū kh .
