Jami' at-Tirmidhi — Hadith #26876

Qutaibah narrated to us, Abther bin Al-Qasim narrated to us, on the authority of Ash’ath, on the authority of Muhammad, on the authority of Nafi’, on the authority of Ibn Umar, on the authority of the Prophet, may God’s prayers and peace be upon him, who said: “Whoever dies He must fast for a month, and let him feed a poor person on his behalf every day. Except from this point of view, and the authentic hadith on the authority of Ibn Umar is authentic. The people of knowledge differed on this matter, and some of them said: The dead. And this is what Ahmad and Ishaq say. They said, “If the dead person had a vow of fasting, he should fast on his behalf, and if he was due to make up for Ramadan, he would feed On his authority. Malik, Sufyan and Al-Shafi’i said, “No one fasts on behalf of anyone.” He said, “And Ash’ath is Ibn Sawwar. And Muhammad is the one I have.” Ibn Abd al-Rahman bin Abi Laila.
