Forbidden fruit is a phrase that originates from Genesis concerning Adam and Eve in Genesis 2:16–17. In the narrative, the fruit of good and evil was eaten by Adam and Eve in the Garden of Eden. As a metaphor, the phrase typically refers to any indulgence or pleasure that is considered illegal or immoral.
Identifying the fruit
Potential forbidden fruits of the Garden of Eden include the apple, pomegranate, the fig, the carob, the etrog or citron, the pear, mushrooms, the quince and, more recently, the datura. The pseudepigraphic Book of Enoch describes the tree of knowledge: "It was like a species of the Tamarind tree, bearing fruit which resembled grapes extremely fine; and its fragrance extended to a considerable distance. I exclaimed, How beautiful is this tree, and how delightful is its appearance!" (1 Enoch 31:4).
One alternative view is that the forbidden fruit is not a fruit at all, but a metaphorical one, possibly the fruit of the womb, i.e. sex and procreation from the tree of life.
The American ethnobotanist and philosopher Terence McKenna speculated that the fruit of the tree is a symbolic allegory for the entheogenic mushroom Psilocybe cubensis, and that the expansion of perceptual and cognitive awareness that resulted from ingestion was responsible for the acquisition of "knowledge".
In Western Europe, the fruit was often depicted as an apple, possibly because of a misunderstanding of, or a pun on mălum, a native Latin noun which means evil (from the adjective malus), and mālum, another Latin noun, borrowed from Greek μῆλον, which means apple. In the Vulgate, Genesis 2:17 describes the tree as de ligno autem scientiae boni et mali: "but of the tree (lit. wood) of knowledge of good and evil" (mali here is the genitive of malum). The larynx in the human throat, noticeably more prominent in males, was consequently called an Adam's apple, from a notion that it was caused by the forbidden fruit sticking from Adam's throat as he swallowed.
Rabbi Meir says that the fruit was a grape, made into wine. The Zohar explains similarly that Noah attempted (but failed) to rectify the sin of Adam by using grape wine for holy purposes. The midrash of Bereishis Rabah states that the fruit was grape, or squeezed grapes (perhaps alluding to wine).
Rabbi Nechemia says that the fruit was a fig, as it was from fig leaves that God made garments for Adam and Eve upon expelling them from the Garden. "By that with which they were made low were they rectified." But the Bible says that it was Adam and Eve who had made their own fig leaf clothing: "And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons." (Genesis 3:7)
Since the fig is a long-standing symbol of female sexuality, it enjoyed a run as a favorite understudy to the apple as the forbidden fruit during the Italian Renaissance. The most famous depiction of the fig as the forbidden fruit was painted by Michelangelo Buonarroti in his masterpiece fresco on the Sistine Chapel ceiling.
The fig tree is also a symbol of knowledge , good or evil. The question asked of Adam , may have been another way of saying, where did you get the knowledge that you were naked ?
Proponents of the theory that the Garden of Eden was located somewhere in what is now known as the Middle East suggest that the fruit was actually a pomegranate, partly because it was native in the region.
A fresco in the 13th-century Plaincourault Abbey in France depicts Adam and Eve in the Garden of Eden, flanking a Tree of Knowledge that has the appearance of a gigantic Amanita muscaria, a psychoactive mushroom. Terence McKenna proposed that the forbidden fruit was a reference to psychotropic plants and fungi, specifically psilocybin mushrooms, which played a central role, he theorized, in the evolution of the human brain. Earlier, in a well-documented and heavily-criticized study, John M. Allegro proposed the mushroom as the forbidden fruit.
In the Book of Enoch  chapt. 1, verse 69: "And the third was named Gadreeel: he it is that showed the children of men all the blows of death, and he led astray Eve, and showed [the weapons of death to the sons of men], the shield and the coat of mail, and the sword for battle, and all the weapons of death to the children of men. And from his hand they have proceeded against those who dwell on the earth from that day and for evermore." Therefore, the fruit of the tree of knowledge of good and evil was flesh and the methods to acquire it.
According to the Quran, Surah Al-A'raf 7:19 describes Adam and his wife in Paradise where they may eat what is provided, except that they may not eat from one particular tree, should they be considered Zalimun. Surah Ibrahim #.14:26 describes the forbidden tree as an evil tree that is forbidden for guidance.
Surah Al-A'raf 7:22 describes the ˈibliːs who misled them with deception, and then it was Adam who initiated eating from the forbidden tree. Then when they tasted of the tree, that which was hidden from them of their shame became manifest to them and they began to cover themselves with the leaves of Paradise. And their Lord called out to them: "Did I not forbid you that tree and tell you: Verily, Shaitân is an open enemy unto you?" (Quran 7:19). The Quran holds both Adam and his wife accountable for eating the forbidden fruit. As punishment, they were both banished from Heaven and sent to the Earth where they were forgiven after repenting.
