The Prophet (may Allah's peace and blessings be upon him) stayed for three nights between Khaybar and Madīnah when he married Safiyyah

The Prophet (may Allah's peace and blessings be upon him) traveled and stayed at a place between Khaybar and Madīnah for three days and three nights with the Mother of the Believers, Safiyyah (may Allah be pleased with her), when he married her. He arranged a wedding dinner and told Anas (may Allah be pleased with him) to invite people to eat. There was no meat or bread served at the dinner, due to the Prophet’s poor financial situation.

So, mats were spread out and dates, dried yogurt, and the like were served. The people ate and wondered if Safiyyah had been taken as a wife or a concubine by the Prophet. Then they said: If the Prophet (may Allah's peace and blessings be upon him) screened Safiyyah, she would be one of the Mothers of the Believers, because veiling was obligatory upon them, but if he didn't, she would be a concubine.

They were assured that she was a wife of the Prophet when he screened her and assigned a wide space for her behind him on his camel.
