May the sick combine prayers?
Short answer
The sick may combine Zuhr and 'Asr and Maghrib and 'Isha' if there is considerable hardship in performing each prayer in its time; without hardship he prays each prayer in its time.
Evidence and explanation
The Shaykh linked the permissibility of combining with the presence of hardship, and counted the sick among those with an excuse.
