With regard to the questions that the angels will ask in the grave, this is explained clearly in the following hadeeth:
It was narrated that al-Bara’ (may Allaah be pleased with him) said: We went out with the Messenger of Allaah (peace and blessings of Allaah be upon him) for the funeral of a man from among the Ansaar. We came to the grave and when (the deceased) was placed in the lahd, the Messenger of Allaah (peace and blessings of Allaah be upon him) sat down and we sat around him, as if there were birds on our heads (i.e., quiet and still). In his hand he had a stick with which he was scratching the ground. Then he raised his head and said, “Seek refuge with Allaah from the torment of the grave”, two or three times. Then he said, “When the believing slave is about to depart this world and enter the Hereafter, there come down to him from heaven angels with white faces like the sun, and they sit around him as far as the eye can see. They bring with them shrouds from Paradise and perfumes from Paradise. Then the Angel of Death comes and sits by his head, and he says, ‘O good soul, come forth to forgiveness from Allaah and His pleasure.’ Then it comes out easily like a drop of water from the the mouth of a waterskin. When he seizes it, they do not leave it in his hand for an instant before they take it and put it in that shroud with that perfume, and there comes from it a fragrance like the finest musk on the face of the earth. Then they ascend and they do not pass by any group of angels but they say, ‘Who is this good soul?’ and they say, ‘It is So and so the son of So and so, calling him by the best names by which he was known in this world, until they reach the lowest heaven. They ask for it to be opened to them and it is opened, and (the soul) is welcomed and accompanied to the next heaven by those who are closest to Allaah, until they reach the seventh heaven. Then Allaah says: ‘Record the book of My slave in ‘Illiyoon in the seventh heaven, and return him to the earth, for from it I created them, to it I will return them and from it I will bring them forth once again.’
So his soul is returned to his body and there come to him two angels who make him sit up and they say to him, ‘Who is your Lord?’ He says, ‘Allaah.’ They say, ‘What is your religion?’ He says, ‘My religion is Islam.’ They say, ‘Who is this man who was sent among you?’ He says, ‘He is the Messenger of Allaah (peace and blessings of Allaah be upon him).’ They say, ‘What did you do?’ He says, ‘I read the Book of Allaah and I believed in it.’ Then a voice calls out from heaven, ‘My slave has spoken the truth, so prepare for him a bed from Paradise and clothe him from Paradise, and open for him a gate to Paradise.’ Then there comes to him some of its fragrance, and his grave is made wide, as far as he can see. Then there comes to him a man with a handsome face and handsome clothes, and a good fragrance, who says, ‘Receive the glad tidings that will bring you joy this day.’ He says, ‘Who are you? Your face is a face which brings glad tidings.’ He says, ‘I am your righteous deeds.’ He says, ‘O Lord, hasten the Hour so that I may return to my family and my wealth.’ But when the disbelieving slave is about to depart this world and enter the Hereafter, there come down to him from heaven angels with black faces, bringing sackcloth, and they sit around him as far as the eye can see. Then the Angel of Death comes and sits by his head, and he says, ‘O evil soul, come forth to the wrath of Allaah and His anger.’ Then his soul disperses inside his body, then comes out cutting the veins and nerves, like a skewer passing through wet wool. When he seizes it, they do not leave it in his hand for an instant before they take it and put it in that sackcloth, and there comes from it a stench like the foulest stench of a dead body on the face of the earth. Then they ascend and they do not pass by any group of angels but they say, ‘Who is this evil soul?’ and they say, ‘It is So and so the son of So and so, calling him by the worst names by which he was known in this world, until they reach the lowest heaven. They ask for it to be opened to them and it is not opened.” Then the Messenger of Allaah (peace and blessings of Allaah be upon him) recited (interpretation of the meaning):
“for them the gates of heaven will not be opened, and they will not enter Paradise until the camel goes through the eye of the needle”
[al-A’raaf 7:40]
He said: “Then Allaah says, ‘Record the book of My slave in Sijjeen in the lowest earth, and return him to the earth, for from it I created them, to it I will return them and from it I will bring them forth once again.’ So his soul is cast down.” Then the Messenger of Allaah (peace and blessings of Allaah be upon him) recited the verse (interpretation of the meaning):
“and whoever assigns partners to Allaah, it is as if he had fallen from the sky, and the birds had snatched him, or the wind had thrown him to a far off place”
[al-Hajj 22:31]
He said: “Then his soul is returned to his body, and there come to him two angels who make him sit up and they say to him, ‘Who is your Lord?’ He says, ‘Oh, oh, I don’t know.’ They say, ‘What is your religion?’ He says, ‘Oh, oh, I don’t know.’ Then a voice calls out from heaven, ‘Prepare for him a bed from Hell and clothe him from Hell, and open for him a gate to Hell.’ Then there comes to him some of its heat and hot winds, and his grave is constricted and compresses him until his ribs interlock. Then there comes to him a man with an ugly face and ugly clothes, and a foul stench, who says, ‘Receive the bad news, this is the day that you were promised.’ He says, ‘Who are you? Your face is a face which forebodes evil.’ He says, ‘I am your evil deeds.’ He says, ‘O Lord, do not let the Hour come, do not let the Hour come.’”
