How early marriage encouraged by Islam could be justified while it affects health of mother and child?

Answer 1

The question assumes that early marriage affects negatively the health of the mother and the child and asks for justification to encourage early marriage in Islam while it is the opposite. Early marriage is better for the health of mother and child and that is why it is encouraged in Islam. In addition, early marriage is better for both wife and husband because it allows a good span of time and better chance for both to get medically treated successfully if there is pregnancy health problems. Also, early marriage is better for both man and woman (if affordable) to protect them from illegal sexualexcitements or sexual affairs.

On the other hand, if mother finds health problems due to frequent pregnancy she is allowed, per religion, to control giving birth and to make the necessary precautions to delay pregnancy.
