Sahih al-Bukhari 2122

Ali ibn Abdullah narrated to us: Sufyan narrated to us, from Ubayd Allah ibn Abi Yazid, from Nafi ibn Jubayr ibn Mutim, from Abu Hurayra al-Dawsi, may Allah be pleased with him, who said: The Prophet went out during part of the day. He did not speak to me, nor did I speak to him, until he came to the market of Banu Qaynuqa. He sat in the courtyard of Fatima house and called, “Is the little one there? Is the little one there?” She kept him waiting for a while, so I thought she was dressing him in a necklace or bathing him. Then he came running, and the Prophet embraced and kissed him, saying, “O Allah, love him, and love whoever loves him.” Sufyan said: Ubayd Allah told me that he saw Nafi ibn Jubayr perform witr with one rakah.
