The Ruling on Hiring Christians on the Pretext of Expertise or the Like

Question:
The hiring of Christian workers has become widespread, under the pretext of expertise, agriculture, or something else, to the point that some of them have worked near the borders of Makkah. What is the ruling on this?

Answer:
Hiring disbelievers is one of the great calamities in this Peninsula. The Prophet (peace and blessings be upon him) instructed that they be expelled from the Peninsula and said: . It is the place where revelation descended and the source of the message. Therefore, it is obligatory to purify it from disbelievers, except in cases of necessity: such as one who comes to sell provisions or goods and then returns, or one who comes to meet the ruler as an envoy from his country, or the like.
As for hiring them to work in the Peninsula and reside there, this is dangerous. The apparent evidence prohibits it, except for a need that the ruler specifically identifies as being in the interest of the Muslims: such as a doctor whose services are needed, or a worker whose services are needed to repair weapons, or the like.
For this reason, the Prophet (peace and blessings be upon him) employed the Jews of Khaybar out of necessity, and then 'Umar expelled them. The Messenger of Allah (peace and blessings be upon him) continued to accept the envoys sent from their countries, taking from them and giving to them in return for what they brought to him.
As for hiring them in this manner for service: as drivers, servants, or workers, this is not permissible. It is obligatory for the rulers—may Allah guide them—to restrict this matter and to strive to eliminate and reduce it as much as possible. The Custodian of the Two Holy Mosques has promised to do so—may Allah guide him—and we ask Allah to help in its implementation.
It is obligatory for the community not to be lenient in this matter, and to be a support for the people of good in this matter. Every person who has a company or factory should strive to hire Muslims, even if they are more expensive. Allah will bless him and help him. But the calamity is the weakness of faith. This person claims that the Muslim is expensive, and that person claims that the Muslim goes to pray and wastes some time. This is a great affliction. We seek refuge in Allah.
It is obligatory to hire Muslims, so that the benefit is for the Muslim man or woman, not for the disbelievers. If there are Muslim men or women in the lands of the Muslims, hire them. Muslims are present in Egypt, in the Levant, in Iraq, in India, in Pakistan, in any place. His agent should look for them and strive to hire the good among the Muslim men and women when needed, so that the wealth remains with the Muslims and not with others, and so that only Muslims are hired for this Peninsula.
This is obligatory for the representatives of companies, for the companies themselves, for the institutions, for the state, and for everyone. It is obligatory to advise one another in this matter, to be earnest and to give sincere advice to Allah and His servants, and not to prefer the worldly life with false claims: that these people are cheaper, or: that these people are more sincere, or: that these people are working all the time. All of this is false. The Muslim is more sincere and better. If the Muslim falls short, it is due to the weakness of his faith and the weakness of his Islam. If his faith is strong, he will be more sincere than the disbeliever and will perform the task better than the disbeliever. Therefore, no one fails in a trust except one whose Islam is weak, or who is not a Muslim.
