«فَسَاقَنِي حَادِي السَّغَبِ وَالْقَضَاءُ الْمُكَنَّى أَبَا الْعَجَبِ»
The driver called Hunger and destiny, nicknamed Father of Wonder, urged me onwards.
Ḥādī is one who urges animals along; saghab is hunger; al-mukannā describes someone given a by-name. Hunger is personified as a driver pushing the traveller forward.
Abū al-ʿAjab is a playful personification of strange destiny, not the introduction of a real named traveller. It hints at the unexpected encounter ahead.
