Rasolullah  ()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, 2 angels, Munkar and Nakeer(names of two special Angels), 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 Qura'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 Naker, 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) a silk bedding filled with musk. Rasulullah  ()

On the Day of Judgement, before Allah, no other intercessor will have a greater status than the Qura'an, neither a Prophet nor an angel."
