Compiled by Imam Yahya ibn Sharaf al-Nawawi
عن عائشة رَضِيَ اللهُ عنها، قالت: سَمِعْتُ رسولَ الله - صلى الله عليه وسلم - يقولُ: "لا صَلاَةَ بِحَضْرَةِ طَعَامٍ، وَلاَ وَهُوَ يُدَافِعُهُ الأَخْبَثَانِ". ((رواه مسلم))
I heard the Messenger of Allah (ﷺ) saying, "No Salat (prayer) should be performed when the food has been served, nor should it be performed when a person is in need of relieving himself."[Muslim].
