I recently bought an Islamic colouring book for children called “Allah Made the Sun and the Moon”. It is published by Goodword Books and can be bought for as little as £1.50.
The book contains different pictures of the creation within the Heavens and the Earth and can be completed using the colour-by-numbers instructions. But as a little money saving tip, I like to photocopy pages for my children to use, that way the book can be used again and again.
I photocopied this page about the creation of the Heavens and the Earth and I let Basma decorate it using art and craft things and while she decorated it we talked about how Allah created the Heavens and the Earth in 6 days.
