"The Messenger of Allah ﷺ said: 'When the call to prayer is given, the Shaitan runs away breaking wind loudly. When the Tathwb (Iqamah) is completed, he comes back and whispers to a man in his hear, until he does not know how many (rak'ahs) he has prayed. If any one of you notices that, let him prostrate twice.'" (Using translation from Nasāʾī 1253)
قَالَ رَسُولُ اللهِ ﷺ «إِذَا نُودِيَ بِالصَّلَاةِ أَدْبَرَ الشَّيْطَانُ لَهُ ضُرَاطٌ فَإِذَا قُضِيَ التَّثْوِيبُ أَقْبَلَ حَتَّى يَخْطِرَ بَيْنَ الْمَرْءِ وَقَلْبِهِ لَا يَدْرِي كَمْ صَلَّى فَإِذَا رَأَى أَحَدُكُمْ ذَلِكَ فَلْيَسْجُدْ سَجْدَتَيْنِ»
