Is one who is killed while serving with the United Nations in conflict zones such as Côte d'Ivoire considered a martyr, knowing that his mission often serves the enemies of Islam and his motive is money?

If the soldiers are sent by Islamic countries to maintain security and stop wars, then they are martyrs if they are killed in the course of their work, based on the Almighty's saying: "And if two factions among the believers should fight, then make settlement between them..." [Quran 49:9]. However, if they are working for the benefit of disbelieving nations, they are not considered martyrs.

As for working for money with disbelievers, the majority of scholars permit a Muslim to work as a hired hand for a disbeliever, provided that the work is not forbidden, such as dealing with alcohol, pork, or spying on Muslims. Some scholars also stipulated that the work should not involve personal service that humiliates the Muslim. If the hiring is free from these prohibitions, then it is permissible, and the money is lawful, based on the hadith of Ali ibn Abi Talib, may Allah be pleased with him, with the Jew.

Accordingly, if your work with them is not in something forbidden, then there is no harm in it for you, nor in what you have benefited from it. But if the hiring involves a prohibition, then it is not permissible to engage in that work from the outset. If you have already worked, then take your wages and give them in charity, and do not consider them permissible for yourself.
