Sayyiduna Waki’ bin ‘Addas (may Allah be pleased with him) narrates: He heard his uncle stating that he heard the Prophet Muhammad (peace and blessings be upon him) say: “A Muslim’s dream is one-fortieth part of prophethood, and it remains in its original state as long as a person does not relate it. When he relates it, then it occurs.”
