Optional Fasting on a Journey and Qada’ (compensatory fast) of Fasting Missed on a Journey

3. A number of our people have narrated from Ahmad ibn Muhammad from Muhammad ibn Khalid from Sa‘d ibn Sa‘d al-Ash’ariy who has said the following: “I once asked al-Rida’ عليه السلام, about the case of the three days’ fasting every month, if Qada’ (compensatory fast) is required from a traveler. He (the Imam) said, ‘No, he is not required to fast.’”
