Fasting is one of the Five Pillars of Islam. Making up for missed fasts is a priority. If one is permanently unable to fast due to old age or chronic illness, they must pay Fidya (feeding a poor person for each day).
Fasting & Qaza FAQ
What if I don't know the exact number?
Scholars recommend making a "best estimate" that satisfies your conscience. It is better to fast a few extra days than to miss any mandatory ones.
When can I keep Qaza fasts?
Qaza fasts can be kept on any day of the year except for the five prohibited days: the two Eids (Eid al-Fitr, Eid al-Adha) and the three days of Tashreeq (11th, 12th, 13th of Dhul Hijjah).
Can I combine Qaza with Sunnah fasts?
Most scholars agree that you should prioritize the Qaza fast with a primary intention for it. Some schools allow the reward of Sunnah (like 6 days of Shawwal) to be attained simultaneously, but others require separate fasts.
Does Qaza fast require a continuous chain?
No, Qaza fasts do not need to be kept consecutively. You can keep them whenever you have the health and opportunity to do so.
