Al-Hasan ibn Mahbub, from Abu Ayyub, from Abu Abdillah عليه السلام, peace be upon him: (Imam عليه السلام was asked) about ‘a man on whom was fasting of two straight months in zihar, so he fasted Dhu al-Qadah, and Dhu al-Hijjah entered on him. What can he do?’ Imam عليه السلام said: “He fasts all of Dhu al-Hijjah except the days of al-tashriq, then he makes them up on the first day of Muharram until he completes three days, so he will have fasted two consecutive months.” Then Imam عليه السلام said: “And it is not appropriate for him to approach his wife until he makes up the three days of al-tashriq which he did not fast. And there is no harm if he fasts a month, then fasts some days from the month that follows it, then an illness occurs to him that causes him to cut it off, then he makes it up after the completion of the month.”
