What happens if such days coincide with the day of ‘Id of Fitr, or Adha’, or days of al-Tashriq or a journey or illness; if he owes to fast on such days or its Qada’ (compensatory fasting) and what must he do, O my master?’ He (the Imam) wrote, ‘Allah has exempted him from fasting on all of these days and he can fast one day for (an alternate) one day, if Allah so wills.’ He wrote to him (the Imam) asking, ‘O my master, there is a man who had made a vow and commitment to fast a certain day and on that day he fell on his wife. What is the expiation for it?’ He (the Imam) wrote, ‘He must fast one day for one day and set free a believing slave.’”
