´Aishah narrated that:` The Messenger of Allah said: "Whoever stays with a people, then he is not to fast without their permission."
Shaykh Dr. Abdur Rahman Freywai
Commentary: 1: That is, Abu Bakr al-Madani, who narrated from Hisham, although he is weak, is stronger than Abu Bakr Madani who narrated from Jabir bin Abdullah; his weakness is lighter in comparison to the latter.
Note: (In the chain of narration, Ayyub bin Waqid is a narrator whose hadith is abandoned [matruk al-hadith].)
