"Jamali relates that Shaikh ‘Usman so dearly loved Khwaja Mu‘inu’d-Din that he himself began a journey walking behind his disciple. After travelling some distance he reached a Zoroastrian fire temple. He sat under a tree and asked his servant to bring him some fire. The priests would not allow him to take it. The Shaikh went himself to the fire worshippers. Their leader was seated on a throne with his seven-year old son on his lap. Shaikh ‘Usman asked if their hands were put into the fire would they be burnt. At the feceipt of a negative reply the Shaikh snatched the boy and jumped into the fire with him. After some hours they both emerged unharmed. The head priest embraced Islam and the fire temple was demolished. Shaikh ‘Usman stayed there for about two and a half years. In the Khairu'l-Majalis the Zoroastrian priests are replaced by Hindus and the conversation is reported in the Hindawi."
