This year we added a garland to our Ashura decorations featuring the flood waves from the story of Prophet Nuh (a).
If you would like to read more about Prophet Nuh (a) to your children there is a chapter about him in My Little Lore of Light by Hajjah Amina Adil. This story is also part of our Illuminated Quran Curriculum at this link: 71. Illuminated Quran: Nuh.
We guled pieces of colored paper in layers to represent the waves.
Then we strung the pieces together to represent the profession and end of the flood for Ashura.
