Ruling on making models of the Ka‘bah to explain the rituals of Hajj

It should be noted that the basic principle concerning acts
of worship is that there should be taqwa in the heart and veneration of the
symbols and sacred things of Allah, may He be exalted; anything that
undermines that veneration of His symbols or turns them into something
commonplace, as people do and have become used to doing, should not be
allowed. 

For that reason, more than one of the scholars have stated
that it is not allowed to make models of the Ka‘bah, because that undermines
the veneration of the symbol in the heart. 

Shaykh Ibn ‘Uthaymeen (may Allah have mercy on him) was asked
about a school that teaches the students about Hajj and ‘umrah but the
students do not understand properly; it is permissible to make a model of
the Ka‘bah and holy places in the school so that they can learn in practical
terms and not just theoretically. 

He replied: 

This is not permissible and it is not appropriate at all. The
teacher can draw a picture of the Ka‘bah on the blackboard and say, We
circumambulate it like this… But as for making a model, this to my mind is
turning acts of worship into mere movements with no impact on the heart.

It says in a fatwa of the Standing Committee: It is not
permissible to make models of the Ka‘bah and the (green) dome that is over
the grave of the Prophet (blessings and peace of Allah be upon him).
