Zinā or Zināʾ (Arabic: الزنا‎ ) is generally defined by Islamic Law as unlawful sexual intercourse, i.e. intercourse between a man and a woman who are not married to one another. This encompasses extramarital sex and premarital sex.

Zina falls under the Islamic sexual jurisprudence of Fiqh, which is an expansion of the Sharia code of conduct given in the Qur'an.

Across all four schools of Sunni practice, and the two schools of Shi'a practice, the term zina signifies voluntary sexual intercourse between a man and a woman not married to one another, regardless of whether one or both of them are married to other persons or not. It does not - in contrast with the usage prevalent in most Western languages - differentiate between the concepts of "adultery" (i.e., sexual intercourse of a married man with a woman other than his wife, or of a married woman with a man other than her husband) and "fornication" (i.e., sexual intercourse between two unmarried persons).

Islamic law prescribes punishments for both Muslim and non-Muslim men and women for the act of Zina as interpreted from the Qur'an and the Hadith. In principle it is an extremely difficult offence to prove, requiring four respectable witnesses to the actual act of penetration.

Arabic (العربية al-ʻarabīyah or عربي/عربى ʿarabī) is a name applied to the descendants of the Classical Arabic language of the 6th century CE. This includes both the literary language (Modern Standard Arabic or Literary Arabic, used in most written documents as well as in formal spoken occasions, such as lectures and radio broadcasts) and the spoken Arabic varieties, spoken in a wide arc of territory stretching across the Middle East and North Africa. Arabic is a Central Semitic language, most closely related to Hebrew, Aramaic, Ugaritic and Phoenician. Written Arabic is distinct from and more conservative than all of the spoken varieties, and the two exist in a state known as diglossia, used side-by-side for different societal functions.

Some of the spoken varieties are mutually unintelligible, and the varieties as a whole constitute a sociolinguistic language. This means that on purely linguistic grounds they would likely be considered to constitute more than one language, but are commonly grouped together as a single language for political and/or ethnic reasons. If considered multiple languages, it is unclear how many languages there would be, as the spoken varieties form a dialect chain with no clear boundaries. If Arabic is considered a single language, it counts more than 300 million first language speakers (according to some estimates, as high as 340 million), more than that of any other Semitic language. If considered separate languages, the most-spoken variety would most likely be Egyptian Arabic, with more than 50 million native speakers — still greater than any other Semitic language.

Maher Zain (Arabic: ماهر زين‎ ; born March 16, 1981 in Tripoli, Lebanon) is a Muslim Swedish R&B singer, songwriter and music producer of Lebanese origin. His debut album Thank You Allah, an internationally successful album with strong Muslim religious influences, was released in 2009. He released his follow-up album Forgive Me on April 2, 2012.

Maher Zain and his family moved to Sweden when he was eight years old. He completed his schooling there gaining a Bachelors degree in Aeronautical Engineering. After university he entered the music industry in Sweden and linked up with RedOne, the Moroccan-born Swedish producer.

When RedOne moved to New York in 2006 Maher Zain followed soon after to continue his music industry career in the USA producing for artists such as Kat DeLuna. On a visit home to Sweden he became engaged once more with his Islamic faith and decided to move away from a career as a music producer to become a singer/songwriter of contemporary R&B music with a strong Muslim religious influence.
