The physical, moral and Sharee‘ah-related differences between man and woman are proven by Divine Decree, the Sharee‘ah, and sound ration.

That is, Allah The Almighty has created man and woman as twin-halves of the human species: male and female, as confirmed by His Statement (which means): {And that He creates the two mates - the male and female.} [Quran 53:45] Both participate in maintaining the universe, each in his/her field. They share in maintaining it by worshipping Allah The Almighty, in which there is no difference between men and women in the universalities of religion: Tawheed (Islamic monotheism), creed, articles of faith, submission to Allah The Almighty, reward and punishment, encouragement and admonition in general, in addition to virtue and chastity. There is also no difference between them in the universality of religious law, as regards to all rights and duties; Allah The Almighty Says (what means):

• {And I did not create the jinn and mankind except to worship Me.} [Quran 51:56]
• {Whoever does righteousness, whether male or female, while he is a believer - We will surely cause him to live a good life.} [Quran 16:97]

• {And whoever does righteous deeds, whether male or female, while being a believer - those will enter Paradise and will not be wronged, [even as much as] the speck on a date seed.} [Quran 4:124]

But, Allah The Almighty decreed that man is different from woman in physique, constitution and appearance. Man is more perfect in nature, disposition and physical power than woman, due to what she suffers of menses, pregnancy, the pains of childbirth, suckling, looking after the affairs of the baby, and raising the future generation of the Ummah (Muslim nation). That is why the woman was created from the rib of Aadam (Adam), may Allah exalt his mention. She is a complementary part of him, and man is entrusted to take care of her affairs, guard and protect her, and maintain her as well as their offspring.

This difference in disposition led to differences between them in physical, mental, intellectual, emotional capabilities, and will-power, and that was reflected in the difference in work, performance, and competence. Additionally, modern day scientists have concluded that there are amazing signs of physiological disparity between the two sexes.

The types of difference between the sexes has accounted for a large set of corresponding Sharee‘ah-stipulated rulings. Allah, The Exalted in Honor, the Wise, with His Perfect Wisdom, has enjoined difference, disparity and authority between man and woman in some Sharee‘ah-stipulated rulings in tasks and functions that befit each according to his/her physique, constitution, capabilities and performance, and the aptitude of each of them in his/her respective field of human life, in order for life to be integrated and for each party to undertake his/her task in it.

Allah The Almighty assigned to men rulings that befit their physique, constitution, structure, competence, qualification for performance, patience, endurance and solemnity, and the bulk of their role is outside the home as they endeavor to provide for their household. He did the same with women, to whom He assigned rulings that befit their physique, constitution, structure, competence, qualification for performance and fragile endurance, and the bulk of their job is thus inside the home, looking after the affairs of their household and raising those in it who constitute the next generation of the Ummah.

Allah The Almighty related from a woman her statement (which means): {“And the male is not like the female.”} [Quran 3:36] Exalted be He, to whom belongs the creation and command, ruling and legislation: {Unquestionably, His is the creation and the command; blessed is Allah, Lord of the worlds.} [Quran 7:54]

This is the universal norm of Allah The Almighty in His creation (meaning that whatever Allah The Almighty wills and decrees for his slaves will inevitably occur), constitution and foundations, and His Legislative norm concerning commands, rulings and laws. Both norms meet to serve the benefits of people, the maintenance of the universe, and the organization of the life of the individual, the home, the community and human society.
