(Qawwal). During the 'spiritual concert' (sama') the qawwal may be the means through which the hearer finds Allah in ecstasy. When this occurs it is true sama' because sama' is a bird which flies from Allah to Allah - Allah is the singer and Allah is the hearer. The barakah surrounding and emanating from the qawwal and his musicians is extremely potent. Its effect upon an audience can be profound even when the members of that audience are ignorant of, and oblivious to, the reality within the singer and the music. For the one who has been prepared and purified, through spiritual struggle and the Remembrance of Allah, the speech of the qawwal can send his heart soaring towards the spiritual realm, where a thousand subtleties and delicacies are opened to him.
