Praise be to Allaah.
Pictures are haraam as
stated in the question. From the hadeeth about the curtain which
‘Aa’ishah (may Allaah be pleased with her) used as a screen in her
house, it is clear that pictures are haraam, even those which do not cast
a shadow (i.e., two-dimensional). The fact that these pictures are for
educational purposes does not justify allowing them in this case. Making
images is haraam except in cases of necessity, because in cases of
necessity, things which are ordinarily forbidden may be permitted.
Although some (scholars) permit such pictures for educational purposes, to
be on the safe side, it is better not to allow it, especially since the
aim can be achieved through other means.
