Bakara 41-43:

•  Bunun için de geçmişte size indirdiğim (tevrat'ı) doğrulayıcı nitelikte olan bu vahye inanın, ve onun gerçekliğini inkar edenlerin öncüsü siz olmayın!. Mesajlarımı basit çıkarlar karşılığı satmayın ve Bana, yanlızca Bana karşı sorumluluk hissi taşıyın. Hakkı batılla örtüp de bile bile hakkı gizlemeyin. İlahi düsturları sıkı sıkı takip edin ve karşılıksız yardımda bulunun. Allah(cc)'a rüku edenlerle birlikte siz de rüku edin.

  In order to understand this verse, it should be kept in mind that the Arabs were generally illiterate and uneducated people. As against them, education was common among the Jews, who had among them great scholars renowned even beyond Arabia. That is why the Arabs were overawed by the scholarship of the Jews, more so because their scholars and rabbis made a great show of their learning and piety and reinforced it with the practice of charms and amulets. The people of Madinah in particular were overawed by the learning of the Jews, for they were surrounded by big Jewish tribes and came in contact with them day and night. As a result, they were immensely influenced by them just as illiterate people usually are influenced by the neighbours who are more educated, more civilized and more religious in character.
  Such were the conditions when the Holy Prophet upon whom be peace) presented himself as a Prophet and began to invite the people to Islam; naturally the illiterate Arabs turned to the Jews for guidance in this matter, and said: "You are the followers of a Prophet and possess a Book, so tell us what you think of this man and his teachings, who claims to be a Prophet." This question was repeatedly asked of the Jews by the people of Makkah, and when the Holy Prophet came to Madinah, here also many people visited the Jewish scholars again and again to ask them the same question. But their scholars never gave them the right answer. For they could not say that the doctrine of Tauhid that Muhammad (upon whom be Allah's peace and blessings) was preaching was wrong, nor that the knowledge which he imparted about the Prophets, scriptures, angels, and the Hereafter was wrong, nor that there was something wrong about the moral principles that he taught. They were neither ready to admit in plain words the righteousness of the teachings of the Holy Prophet; nor had they the courage to refute it openly; nor were they willing to profess the Truth candidly. Instead, they devised a subtle strategy to oppose it: they created one suspicion or the other about the Holy Prophet, his followers and his mission; they would concoct allegations against him and his followers and make false propaganda against them or raise frivolous objections so as to involve them in useless discussions. That is why they have been warned not to conceal the truth by covering it with falsehood, nor suppress it by spreading suspicions and by raising silly objections, nor mix it up with falsehood. ET
