Can A Woman Establish Prayer Without Wearing A Headscarf?

Can a woman establish prayer without wearing a headscarf?

A woman who has reached puberty has to cover her body parts completely as required by Islam while establishing prayer just like she should near the men except her mahrams. Head is one of the body parts that should be covered. In a hadith narrated from Aisha (ra), the Prophet Muhammad (saw) said, “ Allah does not accept the prayer of a woman who has reached puberty unless she wears a headscarf.” (Abu Dawud, Salat, 87) Moreover, there are hadiths informing us that the wives of Prophet Muhammad (saw) would cover their heads while establishing prayer in their house, and that he warned the young girls and women who have reached puberty to establish prayer by covering their heads (Abu Dawud, Salat, 87). The practice since the period of Prophet Muhammad (saw) has been the same.
