Which side is preferable for a sick person praying on their side?
Chapter on the Times When Prayer is Prohibited
Al-Mughni
Book of Prayer
Primary text
It is preferable that the sick person prays resting on their right side. However, praying on the left side is permissible because the Prophet (peace be upon him) did not specify a particular side, and the person faces the Qibla regardless of which side they lie on.
