Parallelism: Wealth of Korah
The Torah and Mishnah tells the story of Korah (or Korach) and his rebellion against Moses (Numbers 16:1-35). This story is also replicated in the Qur'an where Korah is transliterated to Qaaroon.
The parallelism between the Qur'an and the Gemara has not escaped noticed, for instance, this site
V'amar Rabi Levi: "masoi sh'lsh me'ot pardot l'vanot hayu maftchot shel beyt g'nazaiv shel Qorach, V'khulhu aqlidei v'qilfei d'ghilda."
And Rabbi Levi said: "The keys to Korah's treasure house was a load for 300 white mules and the keys and locks were leather."It is clear that the Islamic literature, be it the Qur'an or the extracanonical traditions and commentaries, show a great deal of Judeo-Christian influence.”
A check of Tractate Sanhedrin 110a shows this to be indeed the case:
Jewish scholars have noted that the story of Korah’s wealth is not told in the Torah or Mishnah but by sages. Professor Avigdor Shenan says that the Sages present Korach, among others things, as an extremely wealthy man and the phrase “as wealthy as Korach” is used even today.
Professor Shenan also noted that the Jewish sages had two theories about how Korah acquired his wealth.
Joseph’s great wealth, from when he gathered “all the money which was in the land of Egypt and in the land of Canaan” (Bereishit 47:14)”“According to the other opinion, Pharaoh’s wealth reached Korach since he was Pharaoh’s finance minister, “and he had in his hands the keys to his treasures” (Bamidbar Rabba 18:15).”
Here is Professor Shenan’s conclusion about the wealthy Korah story:
Thus, it can be seen that there is little or no basis in the Bible for Korah to be assumed a wealthy man, especially since he fled with Moses during the Exodus. It is unlikely, although Jewish tradition has it, that the Hebrews would have fled in haste from a vengeful Pharaoh and his army carrying a load of treasure.
So where did Muhammad get his idea about Korah being so wealthy that the keys to his treasure house themselves were so heavy that they required the strength of a body of strong men?
Apparently, Rabbi Levi; a third century Haggadist who lived in Palestine and who also made up the story of Korah’s keys, was actually none other than Allah in the flesh.
