She underwent a surgical operation and suspects that she missed some prayers; how should she make them up?

Question:
May Allah reward you with good and do you well. She says: In one of the surgical operations I underwent, I did not remember that I had not prayed on that day. After several months, I remembered that, so I prayed the 'Asr and the Zuhr. I do not know whether I prayed the 'Isha' and the Maghrib or not. What should I do? Should I pray those prayers about which I am in doubt? May Allah reward you with good.

Answer:
If you are not certain that you prayed, it is obligatory for you to make them up, because the default is that the prayer was not performed. So you must make up the prayers you are in doubt about during the time of treatment, because the default is that they remain a debt upon you, and the debt is not cleared except by certainty of having prayed. So you must make up these prayers for which you are not certain, or for which you are not sure, or for which you have a strong suspicion that you prayed them. Yes.
