Annoying thing about indians

same as we find in pronouncing arabic words... the thing is that these words have lost their pronunciation in colloquial urdu...

Kaaf and Qaaf are different...

Qalb = Heart

Kalb = Dog

just one example from arabic using the same set of words.....

Qaaf is pronunced from the depth of throat - in much thicker accent than Kaaf which is pronunced with the front of throat.
