Ahmad ibn Muhammad has narrated from Ali ibn Ahmad from Musa ibn Bakr from Muhammad ibn Mansur who has said the following: “I once asked al-Rida’ , about a man who makes a vow and then fails to fast. He (the Imam) said, ‘My father , would say that he is required to pay one mud (a certain measurement) for every day.’”
