The Messenger of Allah ﷺ came in to visit Juwayria bint Harith on a Friday while she was fasting.He asked her, "Did you fast yesterday?"She replied, "No."He asked, "Do you intend to fast tomorrow?"She replied, "No."He said, "Then break your fast."
أن رسول الله ﷺ دخل على جويرية بنت الحارث وهي صائمة في يوم الجمعة. فقال لها: أصمت أمس؟ فقالت: لا. قال: أتريدين أن تصومي غدا؟ فقالت: لا. قال: فأفطري إذا.
Ahmad (6771) narrated it from Muhammad bin Jafar, who said, Saeed narrated to us, from Qatada, from Saeed bin Musayab, from Abdullah bin Amr, that the Messenger of Allah ﷺ entered upon Juwayria bint Harith. He said, then he related the hadith. Saeed here is Ibn Abu Aruba, who became confused in his memory toward the end of his life. Muhammad bin Jafar is among those who heard from him after this confusion set in, but he was not alone in narrating this, rather a number of people narrated it from Saeed bin Abu Aruba.Among them was Abdah bin Sulayman, from him. Ibn Khuzayma (2162) and Ibn Hibban (3611) narrated it through his route. Among them was also Khalid bin Harith, from him. Ibn Khuzayma (2162) also narrated it through his route. Among them was also Bishr bin Mufaddal, from him. Nasai narrated it through his route in Kubra (2753). Among them were also Ibn Adi and Abdul-Ala, from him. Ibn Khuzayma (2164) also narrated it through their route.Some of these narrators heard from Saeed bin Abu Aruba before his confusion set in, so their corroboration of one another indicates that he was not confused in this particular hadith.However, Ibn Hajar holds the view that the route of Shuba, from Qatada, from Abu Ayub, who is Maraghi Azdi, from Juwayria, is the preserved one, due to the corroboration of Hammam and Hammad bin Salama, from Qatada, in contrast to the hadith of Saeed bin Abu Aruba, from Qatada, from Saeed bin Musayab, from Abdullah bin Amr, that the Prophet ﷺ entered upon Juwayria, and he then related it.He then said, it is possible that Saeed's route is also preserved, for Mamar narrated it from Qatada, from Saeed bin Musayab as well, but he narrated it as a mursal. See Fath al-Bari (4/234).I say, this mursal narration was reported by Abdul-Razzaq (7804), and an addition from a reliable narrator is accepted. Since Qatada narrated extensively, it may be that he narrated it once in this form and another time in that form, and all of it is sahih.
