Is it necessary to adopt modern medical sciences that recommend sleeping on the left side due to its benefits, or to adopt the Prophetic Sunnah that encourages sleeping on the right side?
Source: FtawySummary from Ftawy's records · added here Sep 2, 2026
It was from the guidance and instruction of the Prophet, peace and blessings be upon him, to sleep on the right side and place the right hand under the right cheek, due to the benefits therein. Among these benefits are that it is quicker to awaken, and because the heart is inclined to the right side, it is not weighed down by sleep, and because it is better for the body. Sleeping on the left side is permissible and there is no harm in it, especially if a person needs it for comfort. The most it amounts to is being contrary to what is superior.
