Praise be to Allaah.
It is well known that governments and the peoples under their rule share different kinds of rights and duties, financial, physical and moral. If the situation is as you mention, that the government under whose care you are in Christian, and that it has started to build mosques in the Muslim areas and that it is fulfilling its duties towards those who are under its care, and meeting their needs and providing them with worldly and religious public facilities in return for the Muslims’ doing their duties towards it and the benefits it earns from them, then in this case there are no reservations about you accepting the mosques that it is providing in fulfilment of its duties towards you. But this should not involve any reminder to you of its favours, or expectation of something in return . indeed, you should accept these mosques and ask for more and for the establishment of Islamic schools. You should not be deterred from asking for all your rights, religious and secular, just because you have been given some of them.
You should also cooperate amongst yourselves to establish other facilities such as mosques, Islamic schools and anything else that you need, whilst also taking care that the stewardship and supervision of mosques and schools etc., built for you by the government should be given to Muslims, not to others, so that nothing happens in them that goes against sharee’ah. This is in accordance with the words of Allaah (interpretation of the meaning):
“Help you one another in Al-Birr and Al-Taqwa (virtue, righteousness and piety)” [al-Maa’idah 5:2]
As regards the money that was spent by the government, you do not need to know where it came from, because there is no daleel to suggest that this is necessary.
