Is the discrepancy in the number of daughters mentioned in Jabir ibn Abdullah's hadith due to the narrator's confusion, or does the hadith combine different narrations?

The doubt regarding the wording of the hadith mentioned in the question originated from Hammad ibn Zayd or his students, not from Sufyan ibn Uyaynah or his teacher Amr ibn Dinar. Tracing the narrations suggests that the doubt came from Hammad ibn Zayd himself, as evidenced by the narration of a group of his students reporting the doubt from him. It is mentioned that Hammad ibn Zayd sometimes experienced doubts in narrations due to his extreme meticulousness and verification. Imam Al-Bukhari drew attention to the disagreement between Sufyan ibn Uyaynah and Hammad ibn Zayd regarding some of the wordings in this hadith.
