Questions on the Explanation of the Book of Nullifiers of Islam

Question:
A man who owns a grocery store wrote on the front of his shop, “We do not sell cigarettes, and we do not sell obscene magazines.” Is this action prescribed, or is it considered showing off (riya’)?

Answer:
What is the reason for him to write this? He does not sell them without writing it, and perhaps this is a form of deception, meaning he is not being truthful in this writing. So there is no need for it, and this is an affectation. No one is forcing you to sell cigarettes and obscene magazines, and no one is forcing you to leave them out without writing it.
