Во сколько лет исламская девушка может выйти замуж, минимальный возраст?
In Quran, the "age of marriage" coincides with puberty. Classical Islamic law (Sharia) does not have a marriageable age because there is no minimum age at which puberty can occur. In Islam there is no set age for marriage, the condition is physical (bulugh) maturity and mental (rushd) maturity. So the age is variable to each individual and also can be variant within diffrent cultures and diffrent times.
