Your last word
مَنْ كَانَ آخِرُ كَلَامِهِ لَا إِلَهَ إِلَّا اللَّهُ دَخَلَ الْجَنَّةَ
Man kana akhiru kalamihi la ilaha illa-llahu dakhala-l-jannah.
"Whoever's last words are: La ilaha illa Allah, will enter Paradise."
Narrated by Mu'adh ibn Jabal. Sunan Abi Dawud 3116
A short reflection
The tongue we trained is the tongue that speaks at the end. The people who recite the shahada often during life are the ones who say it without effort at death.
