Asalaamu Alaykum all, I hope you are in the best of health and iman. There is a family that I know (not very well), a relative of mine is their son's tutuor. So I see this child sometimes in my house. Any way, sometimes he wears his school uniform and my brother noticed one day that there was a cross on it. So he asked him why there's a cross on his shirt and the boy said he goes to a catholic school. I was a little surprised. There are couple different Islamic schools for children in our city and this child's family chose to put their son in a christian school. The boy said he doesn't participate in their bible study sessions or any other religious things, but it's still not an environment that's good for a Muslim child that's growing in my opinion. What do you guys think of this? Is this OK Islamically?
