The right time and age of marriage is when a person achieves sexual as well as mental maturity. Mental maturity can mean the possibility of establishing a cordial family life and the ability to fulfil the rights of family members.
The need of the spouse and family is a natural and instinctive need that Allah through His wisdom puts people in and awakens in its own particular time and season and makes its demand. If he responds on time and meets his demand, he will overcome the natural course and make a person perfect. If it lingers or reacts in the wrong and unnatural mode, it deviates from its natural course, the insurgents and not only corrupts itself, but also corrupts a person.
Who can marry?
In order for a man to get the right to take a woman's hand in marriage, Islam has several recommendations. According to Islamic laws, when a boy reaches the age of fifteen or becomes sexually strong, he is equal and reached puberty. But this is not enough to conclude a marriage contract.
In addition to the laws related to puberty, there is the concept of Rushd, which can be translated as "maturity or the ability of reasonable behavior". The husband should be Rashid and wife Rashidaht; So the duties of married life are reasonably fulfilled.
On the books of Islamic law, you can refer to the exact details of physical and mental maturity.
