Can we combine prayers (Dhuhr and Asr or Maghrib and Isha) if we have a fever? If yes, does Asr or Isha salah need to be repeated if our fever goes away after already combining?

Ustadh AbdulAziz al-Haqqan

If you are very sick and need combine, then you can do so, the salah is correct, and there is no need to repeat anything.
