The Prophet Mohammed 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, people return home, 2 angels, Munkar and Nakeer (names of two special angels), come in the grave and try to seperate this handsome man so that they may be able to interrogate the dead man in privacy about his faith.
But the handsomeman 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 in to paradise".
Thereafter he turnes to his dead companion and says,"I am the Qura'an, which you used to read, somtimes in a loud voice and somtimes in a low voice. Dont worry. After the interrogation of Munkar and Nakeer, you will have no grief".
