Hadith 163

Narrated Umm Salamah (RA): She asked the Prophet (ﷺ), "Can a woman pray in a long dress and a veil without wearing a lower garment?" He replied, "If the long dress is ample and covers the surface of her feet." [Reported by Abu Dawud and the Imams graded it Mawquf (a saying of Umm Salamah)].
