أنا إمرأة مؤمنة ..
And in English Alpha-pet:
Ana Emra'a Mou'mina
I will Learn Some Arabic Grammar of That sentence :
I am .. Means : Ana Akoun Where I Means Ana and Am Means Akoun
Woman Means Emra'a
Faith Means Eman
But if you want to give (Faith) returning to (Noun)
You should say Faith Of and it means in arabic (mou'men) But Mou'men is a masculine, Then If You want return it to feminine, You should add sound (a) to (Mou'min) to be (Mou'mina).
So if you want to say I am a woman of faith
It will be ana emra'a mou'mina or Ana Akoun Emra'a Mou'mina
the Both of them is Right :)
