"It is the city in which the sweet savors of reunion have breathed, which have caused the sincere lovers of God to draw nigh unto Him ... "

 
"IT is Our wish to remember the Abode of supreme blissfulness (Ṭihrán), the holy and shining city—the city wherein the fragrance of the Well-Beloved hath been shed, wherein His signs have been diffused, wherein the evidences of His glory have been revealed, wherein His standards have been raised, wherein His tabernacle hath been pitched, wherein each of His wise decrees hath been unfolded.

It is the city in which the sweet savors of reunion have breathed, which have caused the sincere lovers of God to draw nigh unto Him, and to gain access to the Habitation of holiness and beauty. Happy is the wayfarer that directeth his steps towards this city, that gaineth admittance into it, and quaffeth the wine of reunion, through the outpouring grace of his Lord, the Gracious, the All-Praised."
