The Prophet ﷺ said: Allah does not accept the prayer of a woman who has reached puberty unless she wears a veil. Abu Dawud said: This tradition has been narrated by Sa;id b. Abi 'Arubah from Qatadah on the authority of al-Hasan from the Prophet ﷺ.
عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ لاَ يَقْبَلُ اللَّهُ صَلاَةَ حَائِضٍ إِلاَّ بِخِمَارٍ
