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

                Is it haraam to make models of kaba and explain the children the rituals of haj?
Praise be to Allah.
    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).

    And Allah knows best.
