Is it permissible for a sick person who finds difficulty in performing wudu to combine prayers?

Question:
May Allah reward you. Honorable Shaykh, a questioner says: I was sick and bedridden, and I performed wudu with great difficulty. I prayed Maghrib and combined 'Isha with it, praying four rak'ahs. Then my illness worsened, and I was taken to the hospital. After some hours, I felt energetic, so I repeated the 'Isha prayer. Is my action valid? I ask for guidance for anyone in a situation like mine.

Answer:
A sick person combines prayers if he needs to combine them. If combining is a relief for him, he combines. What you did is valid as long as you needed to combine. If you combine, you do not repeat the prayer, because you prayed while you were excused. Combining is permissible for you, and your combining is, praise be to Allah, sufficient. The prayer you combined with Maghrib or with Zuhr is enough, because when you combine, you are excused. If the excuse is removed afterwards, you do not repeat the prayer.
