Answered by Shaykh Faraz Rabbani
Question: What is the ruling on a 10 year old child leading tarawih and other congregational prayers?
Answer: In the Name of Allah, Most Gracious, Most Merciful
Walaikum assalam wa rahmatullah,
It is a condition for the validity of congregational prayer in the Hanafi school that the imam be an adult (i.e. post-puberty).
The sounder position is that this applies to tarawih prayer as well. [Hidaya with Ibn al-Humam’s Fath al-Qadir] However, there is a less sound position adopted by major Hanafis that it is permitted for a discerning child to lead tarawih. Imam Lakhnawi indicates that this may be followed. [Fatawa al-Lakhnawi]
However, it is sounder and more proper for a child not to be appointed imam even in tarawih.
And Allah alone gives success.
Wassalam,
