«فَقَالَ: هَذَا أَبُو زَيْدٍ السَّرُوجِيُّ»
He replied: This is Abū Zayd al-Sarūjī.
Abū Zayd is a kunyah, while al-Sarūjī is a geographical affiliation to Sarūj. Only now does the narrator acquire the name behind the memorable voice and unusual conduct.
The delayed naming matters. Readers have already seen several sides of the character before receiving a simple label for him.
