I had heard a long time ago that there was something, perhaps in the Qur'an or perhaps in the hadith, which mentioned that the non-believers desired some of the knowledge that came to us (with the Qur'an). Is there such a verse or am I remembering incorrectly? It's possible I may have misread an excerpt? (like the part which says "desires after the knowledge that has come to you" but which uses desires as a noun, not a verb).
