Ziyāda, , i, ii, p. 362, 1. 6)Google Scholar, but possibly also that the Mamluk Sultans were considered as representatives of those Fatimid Imams who were believed by al-Qalqashandi and al-Zahiri to survive somewhere in the Maghrib (cf.

^{page 432 note 2} The question how long the northern Nubian kingdom existed and why the riverain strip from Aswān to Dongola has retained its Nubian speech, posed by S. Hillelson in this Journal, 1937, p. 659, is largely solved by the information contained in Ṣubḥ, viii, pp. 5–8. We learn from there that in the fifteenth century (and probably up till the Funj invasion) this strip remained independent, though already thoroughly Muslim, whilst Bedouin tribes settled to the south of it.
