For those of you watching Omar, during the battle of Uhud shown in Omar, you will see a female archer on the Muslim's side.
She gets a closeup, but you don't get to watch her fight in more than maybe one brief scene. I'm fairly sure it's because she's meant to be Nusayba bint Ka'b Al-Ansariyah (may Allah be pleased with her), the Prophet (peace be upon him)'s personal guard in this battle. ^^
This is likely due to the fact that Islamic tradition is almost entirely agreed upon the impermissability of depicting the Prophet, peace be upon him, so that's why he has no actor in these productions. )
Nusayba (may Allah be pleased with her) spends a lot of time defending the Prophet (peace be upon him), staying very close to him, so that's probably why she wasn't shown again, as it would necessitate showing the Prophet.
You can find out more about her here! I just felt like sharing since I find her very interesting. ^_^
And because she's not given a speaking role or shown very much in the show, unlike the poetess and mother-of-martyrs AlKhansaa (I loved studying her and her poetry! <33) and Shifaa the market controller (may Allah be pleased with them both).
In addition, AlKhansaa (may Allah be pleased with her) wrote elegies. In ancient Arabia, men dominated poetry in all the loosely defined "subjects," (yes, even ghazl/love poetry!) save for one: elegies. The writing of elegies and mournful poems were the domain of women. AlKhansaa was an excellent poet and very nearly won the title of the greatest poet among jinn and ins (humans), but lost the title to another poet... I think it was AlMutannaby? In any case, her poetry is some of the greatest. Even the Prophet (peace be upon him) used to encourage her poetry.
