[Machine] It is to speak with words that, if expressed by them, would be lies, then oppose them with other words that agree with those words in wording but contradict them in meaning, so that the listener thinks that was intended. His saying "mandūḥah" which means spaciousness and room, the Shaykh said this is only permissible in order to repel harm and not to cause harm to others. As for causing harm to others, it is not permissible.
