Did I think that man and woman are equal on Islam?
Of course in Islam it is clearly said that man and woman are different, from a physical point of view, the values, and the decisions of the Shari'ah for each it's also have a lot differences.
Logically it is clear that the differences between man and woman are exist, because generally Man physical strength is more perfect than woman. Woman are not as strong as man. Because woman usually experience menstruation, pregnancy, childbirth, breastfeeding, take care of the child who breastfed and educate her children.
That is, why do the people sidy that woman are created from a man ribs. So woman are part of man, followers of man and are a mandate for man. Because man get the trust of taking care of his wife's needs, keeping and providing for him and his descendants.
These differences include differences in ability, whether physical, intellect, thought, feeling, willingness, work, or stamina.
In particular Allah Subhanahu wa Ta'ala also assigns duties to men with laws that accordance with his physical, muscular, ability, power, patience, tenacity and strength of work, for example they have to face the heat of the weather for working outside his home to support his family .
While for the women, Allah Subhanahu wa Ta'ala gives special tasks in accordance with physical, ability, expertise, work power and body resistance is weaker. Allah Subhanahu wa Ta'ala also obliges the women to settle the affairs in the home as well as educate the future generation of his family.
For example, a law devoted to men, one of them is, mens are leaders for their homes. He is responsible for maintaining and controlling the honor of his household. He must prevent and provide protection in order to avoid humiliation and damage in his household. Besides being responsible for providing for his family.
