Lifted from the Islamic section:
The signs of a good end that appear to the dying person are the things that give him glad tidings as he is dying, that Allah The Almighty is pleased with him.

These signs include the following:

1. Uttering the Shaahadah (testimony of faith) when dying
2. Dying with sweat on the forehead
3. Dying on the night or day of Friday
4. Dying as a fighter for the sake of Allah The Almighty
5. Dying of the plague
6. Dying of a stomach disease
7. Dying by being crushed by a falling wall or by drowning
8. Dying in childbirth or pregnancy
9. Death caused by burning, pleurisy and tuberculosis
10. Dying to defend one’s religion, one’s wealth or one’s life
11. Dying guarding the borders of Islam for the sake of Allah The Almighty
12. Dying whilst doing a righteous deed

These are the good signs which point to a good end, but despite that we cannot be certain that a specific person is one of the people of Paradise unless the Prophet sallallaahu`alayhi wa sallam (may Allaah exalt his mention) testified that he will go to Paradise.
