My father is Harun

Safiyyah came from Banu an-Nadir. Her father had been one of its chiefs, and had been killed at Khaybar, and she had been taken captive in that campaign. She was now in Madinah, married into the household of the man whose community had defeated her own.

There is no version of that position that is comfortable, and the reports do not pretend otherwise. Something was said to her about her descent — the substance being that she was a Jewish woman among them.

She was distressed by it, and it was noticed.

The answer she was told to give did not deny anything. It went the other way entirely: that her father was Harun, her uncle was Musa, and her husband was Muhammad ﷺ.

Every part of that is a fact. She did descend from the house of Harun. Musa was of that house. And the third clause settles her standing in the room she was actually standing in.

What makes it worth studying is the shape of the reply. The slight invited her to be ashamed of an ancestry, and the answer was to name that ancestry as an honour — not to change the subject, not to minimise it, and not to attack the person who had said it. The prophets she came from are the same prophets the people insulting her were required to believe in.

The report is in the Sunan literature rather than the two Sahih collections, and the answer is paraphrased here rather than quoted.
