The Book of the Prohibited actions
Abomination of Joining As-Salat (The Prayer) when the Food is ready or when one is in desperate need to answer the call of Nature
عَنْ عَائِشَةَ رَضِيَ اللهُ عَنْهَا، قَالَتْ: سَمِعْتُ رَسُولَ اللَّهِ - صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ - يَقُولُ: لَا صَلَاة بِحَضْرَة طَعَام، وَلَا وَهُوَ يُدَافِعُهُ الأَخْبَثَانِ . ((رَوَاهُ مُسْلِم))
'Aishah (May Allah be pleased with her) said: 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].
