Abū Bakr al-Kalābādhī said in Miftāḥ al-Maʿānī (50/1, hadith no. 52): It was read before Abū Naṣr Muḥammad ibn Ḥamdawayh ibn Sahl al-Muṭawwiʿī—in Muḥarram of the year 328 AH, in Dār Bakkār, while he was looking into his book—: “Maḥmūd ibn Ādam narrated to you: Sufyān ibn ʿUyaynah narrated to us from ʿAmr ibn Dīnār, with this report, except that he said: ‘When he was asked about the lean cows, how could he give the interpretation before they brought him out?’”

This is a strong corroborating chain and a good chain of transmission, for Ibn ʿUyaynah was trustworthy and a leading hadith master. Maḥmūd ibn Ādam, who was from Marw, was trustworthy. Ibn Abī Ḥātim said (4/1/290–291): “He wrote to my father, to Abū Zurʿah, and to me, and he was trustworthy and truthful.” Abū Naṣr al-Muṭawwiʿī was one of al-Dāraquṭnī’s shaykhs, and he said: “He was trustworthy and a leading hadith master.” Thus, the hadith is established by this chain, and all praise is due to Allah.

A similar version of the hadith has also been narrated from Abū Hurayrah, and it has preceded under no. 1867. In some of its chains, there is the additional wording found at the end of the hadith; al-Ḥāfiẓ Ibn Kathīr deemed it objectionable, as explained there.

1946 — “Fast on behalf of your sister.”

Al-Ṭayālisī transmitted it in his Musnad (2630): Shuʿbah narrated to us from al-Aʿmash, who said: I heard Muslim al-Baṭīn relate from Saʿīd ibn Jubayr, from Ibn ʿAbbās, that a woman came to the Prophet, peace and blessings be upon him, and told him that her sister had vowed to fast for a month, but had embarked on a sea voyage and died without fasting. The Messenger of Allah, peace and blessings be upon him, then said ... and he cited it.
