You're a big kid now so you should know. Big kids use the potty when they need to go. Muslims, big or small, must wash properly after they poo or pee. Rhyme along and you'll learn and see

This book, written in rhyme, serves as a gentle and fun introduction to potty training and Islamic toilet etiquette for little Muslims and Muslimahs. It aims to introduce and normalize "Muslim potty training," which includes istinja, to your child. Istinja is the act of cleaning oneself with water and then wiping oneself dry after using the bathroom. Muslims do this to keep themselves physically and spiritually clean and pure or in a state of Tahara.
