The Prophet (ﷺ) asked for his Rida, put it on and set out walking. Zaid bin Haritha and I followed him till he reached the house where Harnza (bin `Abdul Muttalib) was present and asked for permission to enter, and they gave us permission.
Sahih al-Bukhari Book 77, Hadith 11
← Previous Hadith (the wife of the Prophet) The wife of Rifa`a Al-Qurazi came to Allah's Messenger (ﷺ) while I was sitting, and Abu Bakr was also there. She said, 'O Allah s Apostle! I was the wife of Rifa`a and he divorced me irrevocably. Then I married `AbdurRahman bin Az-Zubair who, by Allah, O Allah's Messenger (ﷺ), has only something like a fringe of a garment, Showing the fringe of her veil. Khalid bin Sa`id, who was standing at the door, for he had not been admitted, heard her statement and said, "O Abu Bakr! Why do you not stop this lady from saying such things openly before Allah's Messenger (ﷺ)?" No, by Allah, Allah's Messenger (ﷺ) did nothing but smiled. Then he said to the lady, "Perhaps you want to return to Rifa`a? That is impossible unless `Abdur-Rahman consummates his marriage with you." That became the tradition after him.

Sahih al-Bukhari Book 77, Hadith 10 Next Hadith → A man asked, "O Allah s Apostle What kind of clothes should a Muhrim wear?"
