Kitab-i-Iqan — Paragraph 282

Consider, that even the year in which that Quintessence of Light is to be made manifest hath been specifically recorded in the traditions, yet they still remain unmindful, nor do they for one moment cease to pursue their selfish desires. According to the tradition, Mufaddál asked Sádiq saying: “What of the sign of His manifestation, O my master?” He made reply: “In the year sixty, His Cause shall be made manifest, and His Name shall be proclaimed.”
