My question: Is the following statement true?
"Book of Revelation preaches the Muslim truth regarding modesty."
Please think gradually:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

This sentence is false because there is no evidence of this. The Book of Revelation is known as a Christian book.
Thus, the answer is no.
