Allah has assigned the Angel of Death, along with other assistants to take the souls ( Soul and life are used interchangeably throughout the book unless otherwise specified.) of men when their life span ends.
Say, 'The Angel of Death who is charged with terminating your lives.( Quran- 32:11. The Angel of Death terminates man's life when he collects his soul. )
The Angel of Death pulls out the soul of the unbeliever harshly and roughly, and the believer's soul gently, ( Refer to the ayaat surah 3:93 & 6:50 ) and they give the latter glad tidings upon his death. ( Refer to this in surah 41:30)
The are two angels, Munkar and Nakeer, who question the dead in the grave; they torture the infidels in it. The Prophet, may Allah exalt his mention, described man's condition at the point of death saying:
When a believer is about to leave this world and enter the next, white faced angels descend from the heavens to attend him.Their faces are like the sun. They bring along with them shrouds and perfumes from Jannah, and sit by his side. They are as many as the sight can reach. The Angel of Death, may Allah exalt his mention, sits by his head and says, 'O good soul, come out to enjoy the forgiveness and pleasure of Allah.
'The Prophet may Allah exalt his mention, went on to say, "The soul comes out rolling down like a drop of water rolling out of a pitcher. When he holds it, the angels do not leave it in his hand for a flicker of an eye. They take it, place it in that shroud, and perfume it. It then emits a fragrance like the best musk that can be found on earth." He said, "They then take it up to heavens,where no group of angels that they pass by but ask, 'Who is this good soul?' They say so & so, the son of so and so, calling him by the best of names that he used to be called in this world.Then they go up to the lowest heaven and ask permission to enter it; and its gate will be opened for them. Angels who are nearest to the next Heaven will accompany him to see him ascent to the upper Heaven, until they finally take the soul up to the seventh Heaven.
Then Allah, Azza wa Jall ( Extolled be His Glory) says, 'Place the record of My slave in the highest rank, but take him back to earth; for from it I created them, and into it I will turn them, and from it I will bring them forth again.'
The Messenger of Allah, may Allah exalt his mention, said: 'When the soul is taken back to join its body, two angels will enter his grave, make him sit down, and ask him, 'Who is your Rubb?' He says, 'My Rubb is Allah.' 'What is your Deen. 'And, 'Who was that man who was sent to you?' He says, 'The Messenger of Allah, may Allah exalt his mention.' Finally, they will ask him, 'How do you know?' 'I read the Book of Allah, believed in it, and believed it', he answers. Allah will say, 'My slave has told the truth. Give him bedding from Jannah, put on him a fragment from Jannah, and open up for him a window to Jannah.' The Prophet, may Allah exalt his mention, went on , 'through which a breeze wafts at him fragrance from Jannah. His grave expands as far as his sight can reach.' He further said, 'Then a handsome man beautifully dressed, and perfumed comes to him and says, 'Rejoice in what awaits you. This is your promised day.' He asks him, 'Who are you? Your face foretells nothing but good news.' He says, 'I am your good deeds.' At that point, he says, 'O my Rubb! Let the Final Hour come to pass so that I may return to my family and property.'
