Islamic family jurisprudence

[1][2][3] It contains pubertal, marital, sexual, child upbringing, adoption and fostering, inheritance, criminal and other related subjects.

[4] The subject mainly discusses on foster relationship, marriage, divorce, Ila, li'an, Raj'ah, Khul', Zihar, Iddah, custody and maintenance of children etc.

[10][8][11] In Islamic law (sharia), marriage (nikāḥ نکاح) is a legal and social contract between two individuals.

A formal, binding contract – verbal or on paper[16] – is considered integral to a religiously valid Islamic marriage, and outlines the rights and responsibilities of the groom and bride.

[29][30] While most traditions discourage celibacy, all encourage strict chastity, modesty and privacy with regard to any relationships between genders, holding forth that their intimacy as perceived within Islam – encompassing a swath of life broader than sexual activity – is largely reserved for marriage.

[52] The Quran disapproved of the promiscuity prevailing in Arabia at the time, and several verses refer to unlawful sexual intercourse, including one that prescribes the punishment of 100 lashes for fornicators.

[53] According to traditional jurisprudence, zina must be proved by testimony of four eyewitnesses to the actual act of penetration, or a confession repeated four times and not retracted later.

[54] Making an accusation of zina without presenting the required eyewitnesses is called qadhf (القذف), which is itself a hadd crime.

Raḍā or riḍāʿa (Arabic: رضاع, رضاعة  pronounced [rɪˈdˤɑːʕ(æ)], "breastfeeding") is a technical term in Sunni Islamic jurisprudence (fiqh) of family meaning "the suckling which produces the legal impediment to marriage of foster-kinship",[57] and refers to the fact that under Sunni jurispurdence, a wet nurse is considered related to the infant she nurses.

The term derives from the infinitive noun of the Arabic word radiʿa or radaʿa ("he sucked the breast of his mother").

It is often called Mīrāth, and its branch of Islamic law is technically known as ʿilm al-farāʾiḍ (Arabic: علم الفرائض, "the science of the ordained quotas").
