Given the task definition, example input & output, solve the new input case.
You are given a sentence in Persian. Your job is to translate the Farsi sentence into Japanese.
Example: ما آواز خوندیم ، و خوندیم ، آواز خونديم ، و بطور شگفت انگیزی اعتماد جدید رشد کرد ، و درواقع دوستی شکوفه زد.
Output: 私たちはただひたすら歌い続けましたすると驚くことに信頼が芽生え友情が花開いたのです
The Farsi sentence is correctly translated into Japanese, because the meaning is preserved.

New input case for you: اما خوشبختانه ، هرگز ازش استفاده نکردند.
Output:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
