The Shaykh : And as for the third hadith: the hadith of 'Aishah (may Allah be pleased with her), that the Prophet (peace and blessings be upon him) said: Sahih Muslim 1147 If it happens that a man breaks his fast in Ramadan because he is traveling, then he is negligent after Ramadan and does not make up the fast, because it is permissible for a person to delay making up the fast until Sha'ban, but he dies before making up what is due from him, then his guardian fasts on his behalf, meaning his heir, whether a mother, father, son, daughter, or wife. This is not on the basis of obligation, but on the basis of recommendation. If his guardian does not fast, he feeds a poor person on his behalf for each day.
Likewise, if he had an expiation due and he died before performing it, while being able to do so, then his guardian fasts on his behalf.
Likewise, if he vowed to fast three days and was able to fast them, but died before fasting, then his guardian fasts on his behalf. If he does not do so, he feeds a poor person for each day.
'A'isha (Allah be pleased with her) reported Allah's Messenger (ﷺ) as saying: If anyone dies in a state (that he had to complete) some fasts, his heir must fast on his behalf.
من مات وعليه صيام صام عنه وليهLikewise, if he had an expiation due and he died before performing it, while being able to do so, then his guardian fasts on his behalf.
Likewise, if he vowed to fast three days and was able to fast them, but died before fasting, then his guardian fasts on his behalf. If he does not do so, he feeds a poor person for each day.
