The tenth question of Fatwa no.
should I treat a Christian neighbor or a colleague at school? Is it permissible to visit them and congratulate them on their holidays?
It is permissible to treat Christian neighbors kindly and help them with permissible matters, do good towards them, and visit them to call them to Allah (Exalted be He), perhaps Allah will guide them to Islam. It is not permissible however to attend celebrations of their feasts, congratulate them or take them as friends.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
