“The Messenger of Allah ﷺ forbade a man from eating while lying down on his face.”  

ابن ماجة:٣٣٧٠حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا كَثِيرُ بْنُ هِشَامٍ حَدَّثَنَا جَعْفَرُ بْنُ بُرْقَانَ عَنِ الزُّهْرِيِّ عَنْ سَالِمٍ عَنْ أَبِيهِ قَالَ

نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يَأْكُلَ الرَّجُلُ وَهُوَ مُنْبَطِحٌ عَلَى وَجْهِهِ
