I want to know the answer to the following question:
Until what day is the Quran believed to be in effect?
All the background I'm provided with is that "The concept of inimitability originates in the Quran where in five different verses opponents are challenged to produce something like the Quran: "If men and sprites banded together to produce the like of this Quran they would never produce its like not though they backed one another."". Is that enough to answer the question?
Answer: no
