What is the ruling on non-Muslim labor?

Question:
He says: We have laborers in our country who do not believe in Allah. Are we responsible for them on the Day of Resurrection? And is it obligatory to call them to Islam?

Answer:
The obligation of da'wah, yes, da'wah is obligatory. It is not permissible, it is not permissible to bring non-Muslim laborers into the lands of the Muslims. It is not permissible. There is plenty of Muslim labor; bring in Muslim labor, do not bring in non-Muslims. They enter the lands of the Muslims, not the Arabian Peninsula.
The Prophet (peace and blessings be upon him) said, "Drive them out" , and he said, "Two religions will not remain in the Arabian Peninsula." Yes. How do we answer regarding the Arabian Peninsula? Do we let them enter it? The Messenger said, "Drive them out." Yes. Honorable Shaykh, may Allah grant you success.
This is not to be understood as the ignorant understand it, who kill diplomats and kill the messengers who send messages to the rulers, or kill the musta'min (non-Muslims granted safe conduct) who enter with safety. This is not permissible.
The life of the believer is the same as the life of the mu'ahid (protected non-Muslim). The same for the mu'ahid; whoever kills a mu'ahid will not smell the fragrance of Paradise, even though its fragrance can be found from a distance of seventy autumns. It is not permissible to kill a mu'ahid or a musta'min.
So there are covenants between us and them, there are covenants between us and them, there are worldly interests between us and them for which they come. They go to their countries as messengers or merchants. But do we bring them in as craftsmen? No, that is not permissible. Yes.
