A drum which is open from one side
Question

                There is a kind of drum which is covered on one side, and the second side is covered apart from a small opening. Is this similar to the daff?
Praise be to Allah.This is more like the 
    tabl (a kind of drum which is covered on both sides) and may be worse, 
    because the sound comes out from this small opening which makes the sound 
    more refined than if it was all sealed or all open. So it is not permissible 
    to use this drum in the same manner as the daff is used, because the daff is 
    not as bad, undoubtedly, whereas this gives a very refined tone and makes it 
    more entertaining and intoxicating.
