The concept of rijal and nisaa traditionally expresses gender roles in Quran. However, this may not be true for the following reasons:
1. There is another pair which shows biological gender and that is dhakr and untha which connotes biological gender as 42/49-50 and 49/13 suggests.
2. Words like ‘nisaa’ikum’ (your nisa) is present in passages which are for believers (start with ya ayyuhalladhina amanoo). If nisa denoted biological gender then the passage would have started with ‘ya ayyuhall rijalun min al mumineen).
3. Nisa is used to be opposite of ‘ibna’ (which is used to connote movements, vitaulity) and also qawm (which is use to connote people who are standing for something.
