We know that we shouldn't tell other people about the sins we do secretly, and there is a sahih hadith in this connection. But what if someone instead ASKS you whether or not you do that sin? Should we then lie and say no?
Suppose that someone asks me, "Do you pray?" and in those days I happen to be not praying any single prayer. Should I say yes?
Or if someone asks me whether or not I do that secret practive everyone does or watch illicit stuff, should I say "No, I don't," even though I do it everyday all the time?
To answer someone's questions such as the above ones become more difficult for someone who is known to be more religious than those around (for example, has a beard, wears hijab, etc.), and even more difficult if you want to actually stop the other person from doing a haram thing (while you yourself do it).
Please let me know what you think, and whether there is an Islamic injuction from the Qur'an or sunna on this one or not, so that I should know what to say next time when someone asks a question like this to me.
