Q. At what age can you start to call the adhaan?
A. It will be permissible for a person to start calling the Azan when he reaches an age where he can call the Azan properly, is fully aware of its proper timings, and is also acquainted with its importance and sacredness in Islam. Hence, a child who has not yet reached the age of puberty, will be allowed to call the azan when the above guidelines are fulfilled.
And Allah knows best.
