Muwatta Malik, 323

Yahya related to me from Malik from Muhammad ibn Zayd ibn Qunfudh that his mother asked Umm Salama, the wife of the Prophet, may Allah bless him and grant him peace, "What clothes can a woman wear in prayer?" She said, "She can pray in a shift that reaches down and covers the top of her feet

Mouhammad Ibn Zaid Ibn Quonfoz a rapporté que sa mère a demandé à Oum Salama la femme de Prophète (salallahou alayhi wa salam) (Sur lui la grâce et la paix d'Allah) «Que doit mettre une femme pour prier»? Elle lui répondit: «elle doit mettre le voile, porter la longue robe qui cache les parties postérieures de ses pieds»
