The male moved on and urged her forward; whenever she hesitated or fell behind, taking the lead was his established habit.
Fa-maḍā and qaddamahā are consecutive actions: moving ahead and bringing the female forward. ʿArradat expresses reluctance or drawing back. The final phrase about proceeding refers to the male’s habitual action when the female falls behind.
