And also what Ali ibn al-Hasan ibn Faddal narrated from Amr ibn Uthman, from al-Hasan ibn Mahbub, from Abdullah ibn Sinan, who said: I (narrator) asked Abu Abdillah عليه السلام, peace be upon him, about ‘a man who fasts a fast which he has appointed upon himself, or fasts the sacred months, then a month and two months pass by him without him making it up.’ He (narrator) said: “So Imam عليه السلام said, ‘He does not fast while travelling, and he does not make up anything from voluntary fasting except the three days which he used to fast in every month. And he should not make it like the obligatory, except that I love for you to continue upon righteous action.” Imam عليه السلام said: “And the one responsible for the sacred months which he used to fast, it suffices him to fast, in place of each month from the sacred months, three days.”
