It is also transmitted that to begin with Qāḍī ‘Ezz al-Dīn was extremely opposed to the samā’ [devotional, ecstatic dance and recitation] of the dervishes. One day [Jalāl al-Dīn Rūmī] Mowlānā, having become greatly aroused with passion, came forth from his madrasa while performing the samā’. He entered the chamber of Qāḍī ‘Ezz al-Dīn and, shouting at him and grabbing him by the collar, he said: ‘Get up! Come to the banquet of God!’ He then dragged him to the gathering of ‘the lovers’ and revealed to him what was appropriate to ‘Ezz al-Dīn’s capacity. The latter tore his robe and joined in the samā’, spinning about and letting out shouts. In the end, he came to experience devotion and become a disciple in complete sincerity.
