Question Summary:
Missed fasts, kaffārah

Question Detail:

 
2007 & 2008 Ramadan,Sexual intercourse several times on several days during Ramadan, while fasting. The couple were NOT married.
2009 to 2012 Ramadan,Sexual intercourse several times on several days during Ramadan, while fasting. The couple IS married.
Both have repented (Tawba) sincerely and Inshallah will never do it again. 
In addition, both the couples when they were younger, missed several Ramadan fast intentionally without a valid reason. Also few times they thought that their fasting was broken due to bleeding and thus started eating.
The couple realises that they have to fast 60 days consecutively +1 day, but how many in total do they have to do? Inshallah, the Guy is healthy and is capable, however the wife is very weak in health, occasionally faints, is low in iron, etc. So please give a detailed solution for both. 

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa rahmatullāhi wa barakātuh.
In principle, if one did not fast in one of the days of Ramadān, meaning, he did not even make the intention to fast on that day, he will only have to make qadā’ and not kaffārah. If on the other hand, one did start the fast on a day of Ramadān, and then he deliberately broke it by sexual intercourse, eating or drinking, he will have to make both qadā’ and kaffārah.
In the situation in question, both husband and wife will have to apply their discretion to determine the number of fasts of Ramadān they did not observe or which they deliberately broke by sexual intercourse or otherwise after reaching the age of puberty.
For each of these fasts, they will have to perform one make-up (qadā’) fast. For example, if they missed or broke 20 fasts of Ramadān, they will have to perform 20 days of fast with the intention of making qadā’ of Ramadān. These fasts do not have to be performed consecutively.
As far as kaffārah is concerned, only one kaffārah will suffice for all the fasts of Ramadān that were broken by sexual intercourse, eating or otherwise, even if over multiple Ramadāns.[1]
Kaffārah equates to sixty consecutive fasts. One must choose a time when the fasts will not be interrupted by the days of ‘Īd al-Fitr or ‘Īd al-Adhā. If for any reason (besides hayd) there is an interruption in the fasts of kaffārah, one will have to restart the sixty day period.
If the wife is genuinely unable to do this, she must give sixty poor people half a sā‘ of wheat each, or its monetary equivalent.[2] Half a sā‘ of wheat is approximately 2.25 kilograms.[3] Alternatively, she may feed the same sixty poor people to their fill for two meals of a day.
And Allah Ta‘ālā Knows Best
