It says something like "say mock [as you wish]." in part of it in Sahih International translation
We should not assist in sinning
We should command good and forbid evil
So how do we tell munafiqs "mock [us/Islam/Muslims]? mocking is a sin and not a good act.
How is it explained?
And do not say it is abrogated JUST BECAUSE it seems to contradict other verses. This is not a convincing method if used without evidence (hadith evidence).
