The Oxford English Dictionary gives no definition of Zina.
Zina refers to sexual relations with someone other than one’s spouse in marriage and is considered a major sin in Islam.
The term Zina should not be used without a clear explanation as to its meaning.
According to Aysha Hidayatullah, the reason why Zina is considered a major sin is because it “undermines the basic foundation of Muslim societal organization – the legal contract by which two partners are bound to each other by clearly delimited rights and obligations,” i.e. marriage. [1]
