A. (#DrZakirNaik): As far as rules of the different countries are concerned, in India the age of adulthood is 18, in Indonesia it is 19, in UK its 16 years of age. Every country the age maturity what the government or the people of that country or the law have set its different depending upon their own understanding. But in Islam fasting becomes compulsory, Salaah becomes compulsory, the acts of worship become compulsory once the person reaches the age of puberty. And there are basically three criteria if anyone of these 3 criteria are fulfilled then the person is said to have reached the age of puberty.
- Growth of coarse pubic hair around the private parts
- The person reached the age of 15
- There is emission of semen in a wet dream or otherwise. If it is female then she starts her menstrual cycle. The day the girl starts her menstrual cycle, she is supposed to reach the age of puberty irrespective she may be below the age of 10.
