Allama Ibn Hazm Al Andalusi (ancient Spain) رحمہ اللہ said :
وأن الجن حق وهم خلق من خلق الله عز وجل؛ فيهم الكافر والمؤمن؛ يروننا ولا نراهم؛ يأكلون وينسلون ويموتون
And the Jinn are Haq, they are one of the creations of Allah Azzawajal, there are both believers & disbelievers amongst them, they see us while we can't see them, they eat, mate and die.
[Al Muhalla bil Aathar 1/33]
Dawood narrates from Amir wo said
They (the Jinn) asked him (the Holy Prophet) about their provision and he said: Every bone on which the name of Allah is recited is your provision. The time it will fall in your hand it would be covered with flesh, and the dung of (the camels) is fodder for your animals.
Then Messenger of Allah صلی اللہ علیہ وسلم said:
فَلاَ تَسْتَنْجُوا بِهِمَا فَإِنَّهُمَا طَعَامُ إِخْوَانِكُمْ "
Don't perform istinja with these (things) for these are the food of your brothers (Jinn).
[Sahih Muslim 450]
