Ground-setting morality, as a part of Islamic morality, concerns the virtue and moral behavior derived from the doctrine of Mahdism which provides personal and social circumstances of waiting for Imam Mahdi's emergence. In ground-setting morality, the ethical act leads to reaching true prosperity, which is realized in the emergence of Imam Mahdi.Historically, the family ethics has been a serious consideration for Infallible Imams and ethics scholars in the domain of ethics. It has been also a part of practical wisdom (housekeeping), which is today, in the field of applied ethics. Applied ethics is comprised of various fields such as spouse ethics, marriage ethics, sexual ethics, management ethics, motherhood ethics and education ethics. In this paper, after a review of basic knowledge and understanding of the concepts of family, morality, ethics and religion, a comprehensive definition of morality ground-setting will be provided, and we tried to consider the virtues and ethical behavior derived from the teachings of Mahdism ethics in seven areas of family (nuclear families). In this context, the attributes and actions of piety, morality, jurisprudence, and the Perseverance, is argued to be derived from the noble tradition: "Aynoony-be-varae-va-ejtehad-va-Sadad" which means but help me and join me in the pursuit of righteousness, piety, at the discretion of effort and hard work, in chastity and in perseverance for the truth. These are the core of ethical ground-setting and their effect and realizations of their work on the relationship between spouses and parents with children. Thereby, explaining this may launch a new initiative to promote and a small step towards the ethics based on Mahdism.
