The ruling on combining two prayers for the sick person

Question:
The questioner, Abu 'Abdullah, says: Honorable Shaykh, for the past three years, health problems have overwhelmed me, my body has become heavy, and I have reached an advanced age. It has become difficult for me, first to perform wudu' (the ablution for prayer), and then to pray. So I pray at home, but, Shaykh, I have started combining the Zuhr (the midday prayer) and 'Asr (the afternoon prayer) because standing is heavy for me. What is your opinion on that? Also, regarding wudu', I pray both prayers with a single wudu'.

Answer:
As for wudu', there is nothing wrong with praying with it as many prayers as you wish, as long as your wudu' has not been broken. So you may pray whatever Allah wills of prayers, obligatory or voluntary. As for combining, do not combine; it is not permissible for you to combine. You should pray every prayer in its time, because combining is permissible for the traveler, and it is permissible for the sick person, and it is permissible between the two evening prayers for rain. So it is permissible. Combining is permissible for a pressing need, and you are not in need of it. Yes.
