أَتَظُنُّ أَنْ سَتَنْفَعَكَ حَالُكَ إِذْ آنَ ارْتِحَالُكَ؟
Do you think your condition will benefit you when the time of departure arrives?
A-taẓunnu challenges a false presumption. Āna means that the appointed time has come, and irtiḥāl is departure or setting out; here the journey is the end of earthly life.
Ḥāl / irtiḥāl echo each other in sound while setting present self-confidence against the unavoidable moment of departure.
