«لَيْسَ إِلَّا الْعَجُوزُ» … «مَا دُونَهَا سِرٌّ مَحْجُوزٌ»
There is no one here but the old woman; no secret need be kept from her.
Al-Ḥārith says only the elderly woman is present; Abū Zayd responds that nothing must be concealed from her. Sirr maḥjūz is a guarded secret. The exchange shows her privileged place in his confidence, but does not by itself establish any particular family relationship.
