Tajāwaztu is the first-person singular perfect of Form VI from the root j-w-z: “I crossed” or “I passed beyond.” Aḥrāsan and maʿsharan are accusative; the second is coordinated with the first.
Ilayhā means “toward her,” with its feminine pronoun referring to the woman. The syntax separates the destination from the obstacles along the way and clarifies the direction of the narrated movement.
