There is a group of jinns in Medina who accepted Islam, so he who would see anything from these occupants should warn him three times; and if he appears after that, he should kill him for he is a satan.  

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ بِالْمَدِينَةِ نَفَرًا مِنَ الْجِنِّ قَدْ أَسْلَمُوا فَمَنْ رَأَى شَيْئًا مِنْ هَذِهِ الْعَوَامِرِ فَلْيُؤْذِنْهُ ثَلاَثًا فَإِنْ بَدَا لَهُ بَعْدُ فَلْيَقْتُلْهُ فَإِنَّهُ شَيْطَانٌ  

give it a warning for three days; if it appears to you after that, then kill it, for it is only a devil.  

أَنَّهُ دَخَلَ عَلَى أَبِي سَعِيدٍ الْخُدْرِيِّ فَذَكَرَ نَحْوَهُ وَأَتَمَّ مِنْهُ قَالَ فَآذِنُوهُ ثَلاَثَةَ أَيَّامٍ فَإِنْ بَدَا لَكُمْ بَعْدَ ذَلِكَ فَاقْتُلُوهُ فَإِنَّمَا هُوَ شَيْطَانٌ
