Cain and Abel from rabbinic texts?

In answer to the video "Muhammad and Merkabah Mysticism"

Some have attempted to source the Quran's version of the Cain and Abel story, as well as a few other stories, to the Pirke de-Rabbi Eliezer. The passages in question from the Pirke only superficially resemble the Quran. The usual claim of "imperfect borrowing" can easily be dismissed by the fact that similarity doesnt entail borrowing.

Without getting to the issue of textual authenticity and which text predates which, both traditions, Jewish and Muslim might be drawing from earlier, independant sources. 

And once more, similarities doesnt entail borrowing. One first has to establish that the supposed (illiterate) author of the Quran had access to the similarities. One then has to explain how he cherry picked among a long list of books and traditions, besides other philosophies and thought systems, to form a well knit, flawlessly intricate narrative in its literary form that left the masters of eloquence of the time dumbfounded, as well as depth of contents that has not finished unravelling its subtleties. 

Why wasnt the source ever exposed nor came out to denounce him, leaving him reap the fruits of their labor. How wasnt this source detected given the largely exposed lifestyle of the time, the open circumstances in which the prophet lived and received revelation, as well as many other factors, not the least being that the Quran never claims to be relating something unknown in that particular narrative, repeatedly says it is a revelation in a long tradition of revelations. 

This means the superficial similarities might be remnants of revealed truths that eventually found their way into these apocrypha. In those writings from which the Quran supposedly draws, one can many times see how the superficial similarities are poorly weaved into the fabric of the story. The apocryphal writer, or his source, was aware of certain elements of the story but poorly integrated them in the whole account.

This is precisely why the Quran refers to itself as the Muhaymin (Guardian), when talking about the textual and oral traditions contemporaries to it. It points out major mistakes in them, filters the Truth from falsehood 

21:24"this is the reminder of those with me and the reminder of those before me". 

The Quran confirming the past scriptures, as well as any tradition, oral or written, in which divine truths still remain 2:41, means that the principles taught by Muhammad come from a common source, which Muslims believe is the Source of creation, and can be found throughout these textual and oral traditions. This is pointed to in the common phrase "musaddiqan lima bayna yadahi". With the passage of time these traditions were burdenned with additions, suffered from corruption and/or neglectful transmission. The Quran then acts as a criterion that distinguishes truth from falsehood. 

Therefore, and for argument's sake, to Muslims, it is irrelevant whether a story bearing similarities with a Quranic passage was even in circulation during and before Islam. It is even less relevant to Muslims whether the similarities were cannonized in the Bible or not. By what standard is the current Bible canon more reliable than the apocrypha? And what proof is there that the unknown Bible compilers rejected these traditions based on these points common to the Quran? Does the current Bible canon even claim to relate every single aspect of the life of its Biblical characters? Is it quiet possible that during the tumultuous process of transmission of the Bible, more particularily the HB which was lost at least twice as recorded in the Bible itself, some parts of the overall transmitted traditions were retained by the editors charged with reconstituting the lost text, and who reflected their own socio-cultural background in the process? Could they have been Selecting what was appropriate for their storytelling purposes and what was not? Of course from a secular viewpoint, the Quran, as a later text, is irrelevant in determining the authenticity, original versions or actual beliefs of those who originated or penned the previous oral and written traditions, canonized or not. But then so is the NT irrelevant in determining those matters from the HB, just as within the HB itself parts are far removed in time and space from other parts, making certain books insignificant when exploring these matters from earlier or later books. However, as soon as one introduces the divine into the equation, then all groups Jews-Christians-Muslims are equal in their claims as regards the authority of one scripture over another. The only factor from a non-secular view point enhancing one claim over another, would be the group with the most authentic, contradiction-free scripture.

In today's mainstream academia, no Islamicist asserts the Quran was influenced by the textual and oral traditions of its milieu, let alone copies from them. Simply because there is no possibility to know whether the human mind who supposedly authored the text had access to those traditions or understood them. What academics do at most, is present what they see as similarities, without disregarding or minimizing the vast differences. On the other side of the spectrum are Judeo-Christian religious zealots and apologists whose methodology and ideas are vastly inherited from their medieval peers' polemical writings. In order to enforce their untenable, unproven claims of borrowing, they retrospectively cherry pick convenient snippets from within larger stories that have very little to do with the corresponding Quranic passages. Then, not only do they disregard the significant differences loaded with theological meanings, but go on magnifying the tiniest similarities to the maximum so as to serve their paradigm. In the process, they inadvertently attribute to Muhammad an encyclopediac knowledge of texts and traditions, as well as an army of unseen informants from a variety of backgrounds and cultures following him around. This weak methodology can be applied to any thought system so as to build up a case for plagiarism. 

The Judeo-christian scriptures themselves relate, through the successive prophets and inspired personalities, different stories that were known to the addressees. This doesnt mean their statements were inspired by these traditions floating around. Rather, the common truths found between these traditions, and the statements of the prophets come from God. There is a myriad of similarities between the HB and stories, texts, inscriptions, including the Ugaritic mention of Adam and Eve, the Mesopotamian myth of Gilgamesh where he is cheated of immortality by a snake who eats a plant (had Gilgamesh eaten it, it would have made him immortal. The elements are the same but play out differently). There are other such myths circulating in Babylon where the Israelites spent a long time in exile, of a hero tricked out of immortality through the device of a plant/food. One could extend the parallelism with the laws of Hammurabi, or the global flood, among many examples, all predating Moses' supposed writing of the Torah. Some of these similarities might be due, as in the Quran, to being remnants of ancient truths partially preserved by these different cultures. But other biblical parallels with predating writings and traditions obviously are copies of unsophisticated legends floating in the region. The oldest and original account of creation in the Bible isnt found in Genesis but in Isaiah, Job or the Psalms. God in these crude stories divides the seas and fights off aquatic monsters. The same is found in the Ugaritic tablets and in a language very similar to Hebrew, with the myth that creation began when the storm god Baal vanquishing the god of the sea Yam and his sea monster-serpent-dragon helpers. Isa27:1 has a very close wording to what a Canaanite says about Baal 

"When you killed Litan, the fleeing serpent, annihilated the twisty serpent, the potentate with seven heads". 

One shouldnt forget that the canonization of the Bible was a long and controversial process, influenced by men with doctrinal bias, and that the current Biblical text is far from being a valid criterion of what truly constitutes divine knowledge from purely human invention.

The Pirke of rabbi Eliezer was actually redacted at least 200 years after the advent of Islam. Ishmael’s wives are even called Fatima and Ayesha! It is attributed to Eliezer although he wasnt its author except potentially for 2 disputed chapters. In addition various versions of it exist. Nothing of its specific information can be traced, whether from written or oral Jewish tradition, anywhere near the time of the advent of Islam. Other illusive sources from whence the prophet Muhammad supposedly constructed his well knit and consistent Quran, could be, according to the opponents, an approximate mishmash of the various informations found in works as, Targum pseudo Jonathan, which was redacted, edited and reedited, well after Islam, the Midrash Tanhuma/Yelammedenu, dated to the mid-9th century CE and having various recensions including in the Cain and Abel story, and finally the Mishnah Sanhedrin in the bit about preserving a soul, a tradition which the Qurn restores to its original universal connotation.
