This narration contains an error from the narrator, as he misunderstood the sequence. It is not unlikely that he heard Abu Abdullah عليه السلام saying to her: "Wash your head, and when you intend to mount (a ride), wash your body." The narrator mistakenly reversed the order in his report. What confirms this is that Hisham bin Salim, the narrator of this hadith, has also narrated what aligns with the correct version that we mentioned.
