Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "No person who enters Paradise will wish to return to the world, even if he were to be given everything on the face of the earth; except for the martyr, for he will wish to return to the world and be killed ten times because of the honor he sees (in martyrdom)."
