Safiyyah was informed that Hafsah had said about her, "She is the daughter of a Jew." The Prophet ﷺ entered upon her while she was weeping and asked, "What makes you cry?"She replied, "Hafsah said to me that I am the daughter of a Jew."The Prophet ﷺ said, "Indeed, you are the daughter of a prophet, your uncle is a prophet, and you are married to a prophet. So in what does she boast over you?" Then he said, "Fear Allah, Hafsah."
بلغ صفية أن حفصة قالت: بنت يهودي، فدخل عليها النبي ﷺ وهي تبكي، فقال: ما يبكيك؟ فقالت: قالت لي حفصة: إني بنت يهودي، فقال النبي ﷺ: وإنك لابنة نبي، وإن عمك لنبي، وإنك لتحت نبي، ففيم تفخر عليك؟ ثم قال: اتقي الله يا حفصة.
Tirmidhi (3894), Ahmad (12392), and Ibn Hibban (7211) all narrated it from the hadith of Abdul-Razzaq (it is found in his Musannaf [20921]), from Mamar, from Thabit, from Anas, who related it. Tirmidhi said, "Hasan sahih, and it is rare through this route." I say, it is as he said. It is a hadith with a sahih chain of transmission. There has been criticism of Mamar's narration from Thabit specifically, so when his error becomes apparent in a given instance, that particular report is daif, but otherwise it carries a sahih chain. This is why the compilers of the sahih collections, such as Muslim, Ibn Hibban, Hakim, and Diya Din Maqdisi, narrated it from Mamar, from Thabit.To the same effect, it has been narrated from Safiya bint Huyayy herself, who said, "The Messenger of Allah ﷺ came to me. Some words had reached me about Hafsa and Ayesha, so I mentioned that to him, and he said, 'Why did you not say, "How can the two of you be better than me, when my husband is Muhammad, my father is Harun, and my uncle is Musa?"'" It seems that what had reached her was that they had said, "We are more honored in the sight of the Messenger of Allah ﷺ than she is," and had said, "We are the wives of the Prophet ﷺ and the daughters of his uncle."Tirmidhi (3892) and Hakim (4/29) both narrated it via the route of Hashim bin Saeed Kufi, from Kinana, from Safiya, who related it. Hakim remained silent about it. Tirmidhi said, "This is a rare hadith. We do not know it from the hadith of Safiya except through the hadith of Hashim Kufi, and its chain of transmission does not amount to much." I say, Hashim bin Saeed Kufi is daif by the consensus of the scholars, except that Ibn Hibban mentioned him in Thiqat (7/585).Safiya is the daughter of Huyayy bin Akhtab, from Banu Nadir, who were of the tribe of Lawi bin Yaqub, and thus among the descendants of Harun bin Imran, the brother of Musa, peace be upon them both. She had been married to Salam bin Mishkam, and after him Kinana bin Abu Huqayq married her. Kinana was killed on the day of Khaybar, and she was a newly-wed bride, as mentioned in Bukhari (4211), so he took her for himself.Ibn Abu Asim narrated in al-Ahad wal-Mathani (3112), via the route of Qasim bin Awf, from Abu Barza, who said, "When the Prophet ﷺ came down upon Khaybar, Safiya was a bride still in her wedding garments. She saw in a dream that the sun came down until it settled on her chest. She related that to her husband, and he said, 'You desire nothing but this king who has come down upon us.'" He said, "So the Messenger of Allah ﷺ conquered it, and her husband was beheaded as a captive."Safiya had also seen, before that, that the moon had fallen into her lap. She mentioned that to her father, and he slapped her face and said, "You are indeed longing to be with the king of the Arabs." The mark remained on her face until she was brought to the Messenger of Allah ﷺ, and he asked her about it, and she told him.The Prophet ﷺ did not leave Khaybar until Safiya had become pure from her menstruation.
