What is the ruling of Islamic law regarding the death of a grandmother who did not utter the Shahada two days before her passing, despite having uttered it before entering into a coma?

The utterance of the two testimonies by the dying person at the time of death is an indication of a good ending, based on the Prophet, peace and blessings be upon him, saying: "Whoever's last words are 'Lā ilāha illallāh' (There is no god but Allah), will enter Paradise." So, if your grandmother uttered the two testimonies and did not speak after them, then fell into a coma until she passed away, this is an indication of her good ending.
