Angels

We should make sure that the life we lead is one that is in the path of Allah and the Sunnah of our Prophet Muhammad (ﷺ). That life would determine our habits and our purity and that would echo in the last days till we meet our death. So, we have to understand that the way we live determines the way we die. May Allah make us among those who are righteous and of strong faith.

1) La ilaha illaAllah as last words leads to Paradise

Narrated Mu’adh bin Jabal :
The Messenger of Allah (ﷺ) as saying: If anyone's last words are La ilaha ill-Allah (There is no god but Allah)" he will enter Paradise.
Sunan Abu Dawud 3116

2) How Angels deal with the Pious and the Wicked after they Die

By those (angels) who pull out (the souls of the disbelievers and the wicked) with great violence;
By those (angels) who gently take out (the souls of the believers);
Surah An Nazi'at 7:1-2

Those whose lives the angels take while they are in a pious state (i.e. pure from all evil, and worshipping none but Allah Alone) saying (to them): Salamun 'Alaikum (peace be on you) enter you Paradise, because of (the good) which you used to do (in the world)."
Surah An Nafl 16:32

And if you could but see when the angels take the souls of those who disbelieved... They are striking their faces and their backs and [saying], "Taste the punishment of the Burning Fire.
That is for what your hands have put forth [of evil] and because Allah is not ever unjust to His servants."
Surah Al Anfal 8:50-51

O you who believe! Fear Allah (by doing all that He has ordered and by abstaining from all that He has forbidden) as He should be feared. [Obey Him, be thankful to Him, and remember Him always], and die not except in a state of Islam (as Muslims) with complete submission to Allah.

Surah Ali 'Imran 3:102

Everyone shall taste death. And only on the Day of Resurrection shall you be paid your wages in full. And whoever is removed away from the Fire and admitted to Paradise, he indeed is successful. The life of this world is only the enjoyment of deception (a deceiving thing).
Surah Ali 'Imran 3:185

Who, when afflicted with calamity, say: "Truly! To Allah we belong and truly, to Him we shall return."
Surah Al Baqarah 2:156

But you prefer the worldly life,
While the Hereafter is better and more enduring.

Surah Al A’la 18:16-17
Indeed, those who have said, "Our Lord is Allah " and then remained on a right course - the angels will descend upon them, [saying], "Do not fear and do not grieve but receive good tidings of Paradise, which you were promised.
Surah Fussilat 41:30

3) Rememeber Death Often

It was narrated that Abu Hurairah said:
“The Messenger of Allah (ﷺ) said: ‘Frequently remember the destroyer of pleasures,’ meaning death.”
Sunan Ibn Majah 4258
