حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عَبْدُ الْوَاحِدِ بْنُ زِيَادٍ، حَدَّثَنَا مُجَالِدٌ، حَدَّثَنَا أَبُو الْوَدَّاكِ، قَالَ 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 صلى الله عليه وسلم ‏"‏ادْرَءُوا مَا اسْتَطَعْتُمْ فَإِنَّهُ شَيْطَانٌ ‏"‏ ‏.‏ قَالَ أَبُو دَاوُدَ إِذَا تَنَازَعَ الْخَبَرَانِ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم نُظِرَ إِلَى مَا عَمِلَ بِهِ أَصْحَابُهُ مِنْ بَعْدِهِ

Abu al-Waddak said

A young man from Quraysh passed in front of Abu Sa'id al-Khudri while he was praying, and he pushed him back. He then tried again and he pushed him back, doing this three times. When he finished, he said, "Nothing cuts off the prayer, but the Messenger of Allah (ﷺ) said: 'Ward off [what passes in front of you] as much as you can, for indeed he is a devil.'"

Abu Dawud said: If two traditions of the Messenger of Allah (ﷺ) conflict, consideration is given to what his Companions practiced after him.
