Very important Facts, that Muslims of today don't know:
1) In Islamic Sharia, Hijab was ONLY for the free Muslim Women. While there was absolutely NO Hijab for the slave women. And also there was NO Hijab for Non Muslim women.
2) In fact, slave women used to move in the society with naked breasts.
Unbelievable, but 100% true.
All 4 Sunni Imams agree upon it that SATR ستر slave women is like Men i.e. from naval till knees, and thus slave women in Madina used to move with open breasts, and they were sold in markets with open breasts.
3) In fact, Hijab was considered as an HONOUR for free Muslim women. It was introduced in Quran for the purpose of differentiating between Free women and slave women.
Therefore, when slave women tried to take Hijab, then Umar Ibn Khattab used to hit them with stick and took off their Hijabs and use to tell them that they were not allow to equate the free Muslim women, and Hijab is an honour for only the free Muslim women.
But what about Shia Islam?
It is the same for Shia Islam too.
Unfortunately, neither Sunni brothers nor Shia brothers believe me, when I tell them the truth. But I know 100% that I am truthful in this matter and thus I am sad when people deny the truth.
