"In thee (Ṭihrán) the Unseen hath been revealed, and out of thee hath gone forth that which lay hid from the eyes of men."

 

"CALL thou to remembrance, O Land of Ṭa  , the former days in which thy Lord had made thee the seat of His throne, and had enveloped thee with the effulgence of His glory. How vast the number of those sanctified beings, those symbols of certitude, who, in their great love for thee, have laid down their lives and sacrificed their all for thy sake! Joy be to thee, and blissfulness to them that inhabit thee. I testify that out of thee, as every discerning heart knoweth, proceedeth the living breath of Him Who is the Desire of the world. In thee the Unseen hath been revealed, and out of thee hath gone forth that which lay hid from the eyes of men. Which one of the multitude of thy sincere lovers shall We remember, whose blood hath been shed within thy gates, and whose dust is now concealed beneath thy soil? The sweet savors of God have unceasingly been wafted, and shall everlastingly continue to be wafted upon thee. Our Pen is moved to commemorate thee, and to extol the victims of tyranny, those men and women that sleep beneath thy dust."
