"[FONT="]When the son of Adam dies, his body disintegrates and vanishes apart from the tailbone, which is a bone at the base of the spine. When the Resurrection begins, Allaah will cause the bodies to grow by means of rain from the earth which will make these bones grow until each person’s body is restored to the way it was before he died. "
"It was narrated from Mu’aadh ibn Jabal that the Prophet (peace and blessings of Allaah be upon him) said: “The people of Paradise will enter Paradise hairless and beardless, with kohl-rimmed eyes, all thirty or thirty-three years old.” (Narrated by al-Tirmidhi, 2545)."
