There is a man who was in a car accident and almost died. For along time – including the month of Ramadaan – he was in serious condition and in a coma. After that the Almighty and Most Generous Creator granted him healing and he was restored to perfect health. Zzzzdoes he have to make up his fasts and prayers?
If it really happened as you say, that this man had lost consciousness during that period – including the month of Ramadaan – when he was not aware of anything as a result of the accident, then he does not have to make up the fasts and prayers that he missed during the days when he was unconscious. This is according to the more correct of the two scholarly opinions, and is because he was not accountable or required to do those acts of worship during that period.
And Allaah is the Source of strength. May Allaah send blessings and peave upon our Prophet Muhammad and his family and companions.
