It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "A woman came to me and I offered her food. She said: 'I am fasting.' The Prophet (peace and blessings be upon him) asked: 'Is it a make-up fast for Ramadan?' She replied: 'No.' He (peace and blessings be upon him) said: 'Then break your fast, and make it up in its place (on another day).'"
No one narrated this hadith from Amrah (may Allah have mercy on her) except Abdullah bin Abi Bakr (may Allah have mercy on him), and no one from Abdullah (may Allah have mercy on him) except Abu Ubaydah (may Allah have mercy on him), while Ya'qub (may Allah have mercy on him) is alone in narrating it.
