Sahih al-Bukhari, 608

Rapporté par Abu Huraira : Le Messager d’Allah (ﷺ) a dit : « Quand l’Adhan est prononcé, Satan s’enfuit en faisant du bruit pour ne pas entendre l’Adhan. Quand l’Adhan est terminé, il revient, puis il s’enfuit à nouveau quand l’Iqama est prononcée. Après cela, il revient encore jusqu’à ce qu’il souffle des pensées dans le cœur de la personne (pour la distraire de sa prière) et lui fait se rappeler des choses auxquelles elle ne pensait pas avant la prière, ce qui lui fait oublier combien de rak`at elle a prié. »

Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "When the Adhan is pronounced Satan takes to his heels and passes wind with noise during his flight in order not to hear the Adhan. When the Adhan is completed he comes back and again takes to his heels when the Iqama is pronounced and after its completion he returns again till he whispers into the heart of the person (to divert his attention from his prayer) and makes him remember things which he does not recall to his mind before the prayer and that causes him to forget how much he has prayed
