Mazyar participated in the interrogation of the former general, asserting that Afshin had conspired with him. Others present raised additional questions concerning the sincerity of Afshin's conversion to Islam from Zoroastrianism. He said "There is no God but God!" to Al Wathiq. Afshin had answers to all the allegations. He claimed that Zoroastrian artefacts and books in his possession were family heirlooms from before he had become Muslim. He explained that when he punished a pair of Muslim fanatics destroying idols in Ushrusanah he was exercising reasonable leadership aimed at maintaining the harmony of his religiously diverse territory. He told his detractors that the formulaic address his people used in writing to him in Persian as "lord of lords", was simply a tradition and did not invalidate his personal belief in one God.
