Bringing books that contain pictures into the mosque
Question

What is the Islamic view on bringing text-books into the mosque in order to teach students from them, given that the final exams are approaching? Some of the text-books contain pictures and some of the teachers have refused to teach the students in the mosque because of these pictures.
Praise be to Allah.It is not permissible, unless the faces and all distinguishing features are erased, whether the picture is on the cover or inside the book.
