The questioner : The question says: Some people do not fall asleep except on their stomachs; what is the ruling on lying on the stomach in this case?

The Shaykh : It is a sleep that Allah does not like. It is not permissible to intentionally do that. Rather, he must engage in exercise, meaning that worship is always contrary to a person's comfort. This is more fitting for... and he should force himself to avoid the obesity that distances... He may turn to his right and left, and there is no objection to that. But to sleep on his stomach while knowing that it is a sleep that Allah dislikes and does not like; this is not permissible at all.
