When you point out the mistakes of Recitation to any body then first listen very attentively to the Recitation. High Hazrat (RA) used to listen to Recitation very attentively. (Even Qari Ilyas Sahab (DB) bends forward towards the reciter when he is listening to the people coming to him for correction of their Recitation.)
