Is the prayer of a Muslim girl who does not wear a hijab not accepted?

A woman's prayer is valid, even if she does not wear the hijab, provided she performs it with all its pillars and conditions. Whoever asks her to abandon prayer because she does not wear the hijab is ignorant, for he is commanding the abandonment of a pillar of religion due to her committing a sin. Allah Almighty says: ﴿Indeed, prayer prohibits immorality and wrongdoing﴾ [Quran 29:45]. And abandoning the hijab is a wrongdoing.
