God (Allah) sent the Revelation of Prophethood to ^Isa (Jesus) when he was thirty years old. Allah revealed to him new laws which abrogated some of the laws revealed to Prophet Musa. Prophet ^Isa conveyed the revelation to the people and called them to believe in his message.
Prophet ^Isa, like all the prophets of Allah, performed miracles. Allah sent all the prophets with miracles as a proof to their prophethood, so the people would witness, know about them, and believe in their prophethood. Many of Prophet ^Isa's miracles were in curing illnesses, to be a stronger proof of his truthfulness, since the people at his time were famous for being knowledgeable in the field of medicine. Prophet ^Isa cured those with seemingly incurable illnesses. Prophet ^Isa cured a man inflicted with leprosy. He put his honorable hand on the face of a man who was born blind and cured his sight. Once Prophet ^Isa supplicated to Allah to bring back to life one person who had died and was being carried to the burial place, and Allah brought this person back to life.
Prophet ^Isa had other kinds of miracles also. He formed the shape of bats from clay and then they would fly away a distance. One of the miracles of ^Isa is mentioned in the Qur'an in Surat al-Ma'idah, Verses 112-114, which tells about one time when Prophet ^Isa and the people who were with him reached to a place where there was not enough food for all the people with him. The students of ^Isa asked him to supplicate Allah for food which would come down on them from the sky. ^Isa made supplication to Allah and the angels brought down the food on a piece of material before the eyes of the people. Hundreds and hundreds of people ate from that food, and there was no sign the food had diminished in quantity. This miracle increased the belief of the believers. The blasphemers however, claimed ^Isa had performer sorcery on their eyes.
After his revelation, Prophet ^Isa lived on earth for about three years. He used to travel from place to place calling people to the proper worship of Allah. He was so detached from the worldly matters that he did not worry that he did not have a house to return to at night. He used to sleep wherever the night would fall on him, whether he was in an open land or in a sheltered place. He wore clothing made out of unwoven wool. He ate from the raw plants of the earth, without desiring to cook them. He did not marry or have children.
