Rasulullah (saw) said: When a man dies and his relatives are
busy in funeral, there stands an extremely handsome man
by his head. When the dead body is shrouded, that man gets
in between the shroud and the chest of the deceased.
When after the burial, the people return home, two angels,
Munkar and Nakeer, come in the grave and try to separate
this handsome man so that they may be able to interrogate
the dead man in privacy about his faith. But the handsome man says,
He is my companion, he is my friend. I will not leave him alone
in any case. If you are appointed for interrogation, do your job.
I cannot leave him until I get him admitted into Paradise.
Thereafter he turns to his dead companion and says,
I am the Noble Qur'an, which you used to read, sometimes
in a loud voice and sometimes in a low voice. Do not worry.
After the interrogation of Munkar and Nakeer,
you will have no grief.
When the interrogation is over, the handsome man arranges
for him from Al-Mala'ul A'laa (the angels in Heaven) silk
bedding filled with musk.
Also Rasulullah (saw) said: "On the Day of Judgement,
before Allah (SWT), no other intercessor will have a greater
status than the Noble Qur'an, neither a Prophet nor an angel."
