Anas bin Malik reported,

The Prophet ﷺ stayed for three days between Khaybar and Madinah, during which his marriage to Safiya bint Huyayy was consummated. I invited the Muslims to his wedding feast. There was neither bread nor meat at it. He ordered that leather mats be spread out, and dates, dried curd, and clarified butter were placed on them. That was his wedding feast.The Muslims said, "Is she one of the Mothers of the Believers, or among those his right hand possesses?" They said, "If he veils her, then she is one of the Mothers of the Believers, and if he does not veil her, then she is among those his right hand possesses."When he set out, he prepared a place for her behind him and drew a curtain between her and the people.

حدثنا محمد بن سلام أخبرنا إسماعيل بن جعفر عن حميد

عن أنس قال

أقام النبي ﷺ بين خيبر والمدينة ثلاثا يبنى عليه بصفية بنت حيي فدعوت المسلمين إلى وليمته فما كان فيها من خبز ولا لحم أمر بالأنطاع فألقي فيها من التمر والأقط والسمن فكانت وليمته فقال المسلمون إحدى أمهات المؤمنين أو مما ملكت يمينه فقالوا إن حجبها فهي من أمهات المؤمنين وإن لم يحجبها فهي مما ملكت يمينه فلما ارتحل وطى لها خلفه ومد الحجاب بينها وبين الناس
