Sleeping on one’s stomach when there is a legitimate reason

 

Alsalam Alykuym

my question is regarding a posting i saw in your website that it is
preffered for a Muslim to sleep on his right side and not on his stomach. Is that true?
and what if a person due to problems with his back can't sleep except on his stomach?

Jazakum Allah Khair

Praise be to Allaah.

If you have no choice but to sleep on your back, there is nothing wrong
with doing so, so long as you are keen to follow the Sunnah and the only reason you cannot
put this particular aspect of it into practice is your illness. And Allaah knows best.
