The Prophet ﷺ said: Nothing interrupt prayer, but repulse as much as you can anyone who passes in front of you, for he is just a devil.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَقْطَعُ الصَّلاَةَ شَىْءٌ وَادْرَءُوا مَا اسْتَطَعْتُمْ فَإِنَّمَا هُوَ شَيْطَانٌ  

A youth from the Quraish passed in front of Abu Sa’id al-Khudri who was praying. He repulsed him. He returned again. He then repulsed him for the third time. When he finished the prayer, he said: Nothing cuts off prayer; but the Messenger of Allah ﷺ said: Repulse as much as you can, for he is just a devil. Abu Dawud said: If two traditions of the prophet ﷺ conflict, the practice of the Companions after him should be taken into consideration.  

مَرَّ شَابٌّ مِنْ قُرَيْشٍ بَيْنَ يَدَىْ أَبِي سَعِيدٍ الْخُدْرِيِّ وَهُوَ يُصَلِّي فَدَفَعَهُ ثُمَّ عَادَ فَدَفَعَهُ ثَلاَثَ مَرَّاتٍ فَلَمَّا انْصَرَفَ قَالَ إِنَّ الصَّلاَةَ لاَ يَقْطَعُهَا شَىْءٌ وَلَكِنْ قَالَ رَسُولُ اللَّهِ ﷺ ادْرَءُوا مَا اسْتَطَعْتُمْ فَإِنَّهُ شَيْطَانٌ
