Is it permissible to bring in non-Muslim servants to homes on the basis of the Prophet’s use of a Christian slave?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: Does the use by the Prophet (peace and blessings be upon him) of a Christian slave indicate the permissibility of bringing in non-Muslim servants to homes, especially if their conversion to Islam is expected?

Answer:
If they are residents of the country, like the Jews in Madinah, there is nothing wrong with employing them. But bringing them in from the lands of the disbelievers is not permissible. It is not permissible to bring in a disbeliever from the lands of the disbelievers to do work that a Muslim can do. However, if the work is something only this disbeliever can do because he is a specialist, there is nothing wrong with continuing to employ him, but only to the extent of the need. Yes.
