Shaykh, my sister studies in a muslim primary school. Today I was checking her English book and found a chapter titled “A Prayer to God.” One line says: “We are your children, you are father of us all.” Is this saying appropriate or should she aviod? and Should I speak to the principal?

This is disbelief, so u should be very careful and advise them immediately as this might have happened due to a mistake.
