A truffle is not a true plant; it is the fruiting body of an underground fungus like mushroom.
Truffles are wildly grow at Gulf deserts, they are form a symbiotic relation with the roots of several plants including particular genus of Helianthemum which is called raqrooq in Arabic.
The plant is not mentioned in the Holy Qur’an.
Narrated by Said bin Zaid: I heard the Prophet Saying, “Truffles are like Manna (i.e. they grow naturally without man’s care) and their water heals eye diseases. Shahih Al Bukhari, book of medicine.
