Is the Call to Prayer of a Child Valid?
Hanafi Fiqh
Answered by Shaykh Faraz Rabbani
Question : Is the adhan of a child valid?
Answer : The adhan of a children who has reached the age of discernment (seven years or older) is valid without being prohibitively disliked. But, it is still superior for an adult to give the adhan. [Fatawa Hindiyya; Ibn Abidin, Radd al-Muhtar]
And Allah alone gives success.
