DEFINITION OF NIKAH (marriage)
Nikah is an Arabic term used for marriage. It means “contract”. (“Aqd in Arabic). The Quran specifically refers to marriage as “mithaqun Ghalithun,”. Which means “a strong agreement”.
“and they have taken a strong pledge (Mithaqun Ghalithun) from you?” (Quran 4:21)
The seriousness of this covenant becomes very obvious when one finds the same term i.e., Mithaqun Ghalithun, being used for the agreement made between Allah and the Prophet before granting them the responsibility of the Prophethood. (Quran 33:7)
The Quran also uses the Arabic word “Hisn”, suggesting “fortress” for marriage. Marriage is considered the fortress of chastity.
