What is the ruling when explicit words for emancipation are used with a non-emancipatory intent?

Primary text

If a master uses explicit words of freedom but intends a meaning other than emancipation—such as calling a slave 'hurr' (free) to signify his high moral character or stating 'Ma anta illa hurr' (You are only free) to mean the slave is disobedient and owes no allegiance—emancipation does not occur according to the established school of thought (Dhahir al-Madhhab). A narration suggests that if the master uses phrasing that allows for an alternative interpretation, such as saying 'Kaannaka hurr' (as if you are free), emancipation may be averted, though this matter is treated with caution because the utterance carries the meaning intended.
