I saw that I went down into an underground room to the grave of contemporary Muslims. The room had a door and the dead were wrapped, each one of them in a white shroud, and arranged on the floor of the room and next to the wall so that the head was against the wall and the feet were in the middle of the room. There were candles burning among the dead.
The second shroud from the door side belonged to the father of my friend named Khaled. There was a lit candle next to it, and the wax was melting. It reached the shroud of my friend Khaled's father, making the shroud completely covered in wax. Khaled was among the people who went down with me to the cemetery. He lay on top of his father's body and hugged him. I tried to convince him to leave his father's body alone. I was upset by the sight of the wax covering his father's shroud. The body next to the door had exposed feet that were being eaten by insects, so one of the visitors covered the feet. The sight of the grave and the candles inside was somewhat frightening, despite it being decorated with candles.
I left this room alone and found myself in front of a room with no walls, as far as the eye could see. It contained the grave of the Prophet (peace and blessings be upon him) and the rest of the companions, who were buried underground in a well-arranged manner. Above each grave was something resembling marble in the form of a rectangle lying on the ground, indicating the direction of their bodies. The first grave on the left was the grave of Lady Aisha (may God be pleased with her), the place where she used to sleep on her bed, but it was slightly tilted. Then there was the grave of the Prophet (peace and blessings be upon him), then the grave of our master Abu Bakr (may God be pleased with him), then the grave of our master Umar (may God be pleased with him), then the graves of the rest of the companions (may God be pleased with them), all of them arranged in a row next to each other and without candles, but the appearance of the grave was beautiful, clean, and tidy, and as far as the eye could see.
I left this large room that contained the graves of contemporary Muslims, the grave of the Prophet (peace and blessings be upon him) and the Companions, and I stood above these graves. It occurred to me that I would be buried between the Prophet (peace and blessings be upon him) and the Companions. What was on my mind at the time was that there was not enough distance between the grave of the Prophet (peace and blessings be upon him) and the Companions to accommodate my body after my death.
