Is it possible for a couple to return to marriage after a divorce that occurred a long time ago?

If a man divorces his wife with the first or second divorce, and her waiting period (iddah) ends, she becomes irrevocably separated from him and cannot return to him except with a new marriage contract. However, if he divorces her with the third divorce, she becomes unlawful for him until she marries another husband in a legitimate, desired marriage that includes consummation. This is based on the Almighty's saying: ﴿And if he has divorced her [for the third time], then she is not lawful to him afterward until she marries another husband﴾, and the hadith of the wife of Rifa’ah Al-Qurazi, whom Rifa’ah divorced three times, and she did not become lawful for him until after she tasted the sweetness of her second husband.
