ender identity does not necessarily or solely determined by biological attributes, but the biological attributes cause the burden of gender. Once a baby/fetus is detected its biological attributes, that moment marks the cultural construction of the child/fetus. If the baby is as a male names and baby boy accessories are prepared, and vice versa. I identified as a girl so the female names and baby girl accessories are prepared. It works this way until the child becomes an adult with a load of gender burdens that must be carried. So the ownership of the penis or vagina can be regarded as a biological event, being born with certain biological anatomy, but it can also be regarded as a cultural event, because it is directly picked up by the gender burden which lives in the community. The principles of gender equality in the Qur'an, among others, equate the status of men and women as slaves ('abid) of God, and as of God's representative on earth (khalifah Allah fi al- ardi) Men and female were created from the same element, then both involved in the cosmic drama, when Adam and Eve were equally guilty of causing them to fall to the earth. Both of them has the potential to obtain achievement in the earth, and equally have the potentional to achieve the consent of God, both in this world and in the hereafter.
