(17) Hadhrat Ali (radhiyallahu anhu) said: "Rasulullah (sallallahu alayhi wasallam) prohibited beating of the duff (drum) and the sound of the flute." (Nailul Autaar)

From this Hadith as well as others, the ambiguity about the duff is eliminated. It is clear from several Ahaadith that the general ruling of prohibition applies to even the duff. However, an exception has been made for o­nly the duff for the Days of Eid and marriage occasions provided no haraam acts are committed. This Hadith has the effect of abrogation. It cancels out the other narrations in which the duff was allowed. The fact that Hadhrat Ali (radhiyallahu anhu) and other Sahaabah too propagated the general prohibition of the duff even after the demise of Rasulullah (sallallahu alayhi wasallam) is sufficient substantiation for the abrogating force of this Hadith as well as other Ahaadith which also mention the prohibition of the duff.
