How Muslims pray, not only in the mosque but at home and elsewhere. We see Muslims praying at home and find out about the Muslim pilgrimage to Mecca (also known as Makkah) for the Hajj. We also see pictures of the Ka'aba, where millions of Muslims go to pray to Allah for his blessing.
Children could think of special places they visit and the reasons they think they are special. They could then compare this with the Muslim pilgrimage to Mecca (also known as Makkah).
