Is it permissible for a wife to mention the names of other women to her husband during intercourse at his request, as he claims it is for pleasure and to affirm that she is the only one in his eyes, while she feels remorse because of it?

This act should be avoided. Some scholars have prohibited a husband from imagining the beauty of a foreign woman while having intercourse with his wife, because that is a means for the heart to become attached to her, and it may lead him to something more grave. If the husband insists on that, he is not to be obeyed, because obedience is in what is right and lawful, and the husband's request for that is not of what is right and lawful, and it may harm the wife.
