Ayesha said, "The Messenger of Allah ﷺ married me in Shawwal and consummated the marriage with me in Shawwal. So which of the wives of the Messenger of Allah ﷺ was more favored by him than I was?"The narrator said, Ayesha used to like having her women relatives enter into marriage during Shawwal.
تزوجني رسول الله ﷺ في شوال، وبني بي في شوال، فأي نساء رسول الله ﷺ كان أحظى عنده مني. قال: وكانت عائشة تستحب أن تدخل نساءها في شوال.
Muslim narrated it in the Book of Marriage (1423) via Waki, who said, "Sufyan narrated to us, from Ismail bin Umaya, from Abdullah bin Urwa, from Ayesha," and he related it.As for what was narrated from Harith bin Hisham, that the Prophet ﷺ married Umm Salama in Shawwal and consummated the marriage with her in Shawwal, this is daif.Ibn Majah narrated it (1991) from Abu Bakr bin Abu Shayba, who said, "Aswad bin Amir narrated to us," who said, "Zuhayr narrated to us, from Muhammad bin Ishaq, from Abdullah bin Abu Bakr, from his father, from Abdullah bin Harith bin Hisham, from his father, that the Prophet ﷺ," and he related it.It has two flaws. The first is Muhammad bin Ishaq, who is a mudallis, and he did not state explicitly that he heard it directly. However, Ibn Saad narrated it (4/8-95) and there he did state it explicitly.The second is the discontinuity, for Abdul-Malik bin Harith has been attributed to his father's grandfather, when he is actually Abdul-Malik bin Abu Bakr bin Abdul-Rahman bin Harith Makhzumi, from his father, Abu Bakr bin Abdul-Rahman, that the Messenger of Allah ﷺ, when he married Umm Salama... and he related it.Malik also recorded it in the Book of Marriage (10), and it has been referenced in its proper place.So the hadith is from the narration of Abu Bakr bin Abdul-Rahman, not from the hadith of his grandfather Harith bin Hisham, so take note of that.However, Malik's hadith came through another route, connected, mentioning Umm Salama.
