وَعَن أبي ثعلبةَ الخُشَنيَّ يَرْفَعُهُ
«الْجِنُّ ثَلَاثَةُ أَصْنَافٍ صِنْفٌ لَهُمْ أَجْنِحَةٌ يَطِيرُونَ فِي الْهَوَاءِ وَصِنْفٌ حَيَّاتٌ وَكِلَابٌ وَصِنْفٌ يُحلُّونَ ويظعنونَ»
Abu Thalaba al-Khushani traced to the Prophet (sallallahu alayhi wa sallam) the saying that the jinn are of three classes, one which have wings and fly in the air, one which consists of snakes and dogs, and one which stay in places and travel about. It is transmitted in Sharh as-sunna.
