Allah’s Messenger (ﷺ) said: “Satan comes to one of you in Salat and blows air in his bottom, so he imagines that he has realised air yet he did not. So if he gets that feeling he should not leave his prayer unless he hears the sound (of the air) or smells its odour.” .
وَعَنْ مُعَاوِيَةَ - رضى الله عنه - قَالَ: قَالَ رَسُولُ اَللَّهِ - صلى الله عليه وسلم -{ الْعَيْنُ وِكَاءُ السَّهِ, فَإِذَا نَامَتْ اَلْعَيْنَانِ اِسْتَطْلَقَ اَلْوِكَاءُ } رَوَاهُ أَحْمَدُ, وَالطَّبَرَانِيُّ وَزَادَ { وَمَنْ نَامَ فَلْيَتَوَضَّأْ }
Narrated Narrated Mu’awiyah (rad):
Allah’s Messenger (saW) said: “The eye (when awake) is the string of the anus (to stop air escaping), and if the two eyes sleep the string is untied”. ”
