Can you sleep on your stomach?

Always try and avoid sleeping on your front. Why? Because the Prophet ﷺ said in a hadith, according to Imam Ahmad, this is how the people of Jahannam, they will lie. And in another hadith, the Prophet ﷺ said in a hadith, according to Imam Tirmidhi, that this is a way of lying that Allah hates. So avoid sleeping on your front. If you have a medical condition, if it's something of need, no problem with that. It's an exception. But the general rule is not to sleep on your front. Rather, the sunnah of the Prophet ﷺ, as we know, is to sleep on the right side.
