Is it permissible to display a righteous deed to the one who asked about it?

Question:
As for righteous deeds, if a person is compelled and asked about them: is there any showing off (riya') in displaying them to him?

Answer:
No, there is nothing wrong with it if he does not intend showing off (riya'); there is nothing wrong with it. If he is asked, "Do you fast on Mondays or Thursdays?" and he says, "Yes," and he does not intend showing off (riya') but intends to give the information, then there is nothing wrong with it.
