Accordingly, women's Hijab goes back to the time of the Prophet (peace be upon him) and is ordained by Allah (Exalted be He), not by the Turks. It is true that women took part along with men in many kinds of work at the time of the Prophet (peace be upon him) like treating the wounded and providing them with water during Jihad (fighting/striving in the Cause of Allah) but they were wearing Hijab, dress modestly and keep away from the causes of suspicion.
It is narrated that Um Sulaym (may Allah be pleased with her) said: We used to go to battles with the Prophet (peace be upon him) to provide water to the wounded, carry water and treat the sick.
This is what they used to do, unlike the women of today, in many socalled Islamic countries, who intermix with men in various fields of work while being Mutabarrijah (a woman who dresses immodestly in violation of the Islamic dress code); a matter that led to the spread of vice, the disintegration of the family and the corruption of society.
