وَحَدَّثَنَا زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنِ ابْنِ عَجْلاَنَ، حَدَّثَنِي صَيْفِيٌّ، عَنْ أَبِي السَّائِبِ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ سَمِعْتُهُ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِنَّ بِالْمَدِينَةِ نَفَرًا مِنَ الْجِنِّ قَدْ أَسْلَمُوا فَمَنْ رَأَى شَيْئًا مِنْ هَذِهِ الْعَوَامِرِ فَلْيُؤْذِنْهُ ثَلاَثًا فَإِنْ بَدَا لَهُ بَعْدُ فَلْيَقْتُلْهُ فَإِنَّهُ شَيْطَانٌ " .
