What age should kids start praying in Islam?

Guidance on When to Start Teaching Prayer

To determine the appropriate age for introducing Salah to your children, it's essential to refer to the teachings of Prophet Muhammad (saw). According to a hadith, you should begin teaching your child to pray when they reach the age of seven, and from the age of ten, they should be encouraged to pray regularly with the understanding that they may face consequences for neglecting it (at-Tirmizi No. 407).
