“God indeed shall make whom He will to hearken, but We shall not make those who are in their graves to hearken.”

"They that have hearts to understand, they that have quaffed the Wine of love, who have not for one moment gratified their selfish desires, will behold, resplendent as the sun in its noon-tide glory, those tokens, testimonies, and evidences that attest the truth of this wondrous Revelation, this transcendent and divine Faith. Reflect, how the people have rejected the Beauty of God, and have clung unto their covetous desires. Notwithstanding all these consummate verses, these unmistakable allusions, which have been revealed in the “Most weighty Revelation,” the Trust of God amongst men, and despite these evident traditions, each more manifest than the most explicit utterance, the people have ignored and repudiated their truth, and have held fast to the letter of certain traditions which, according to their understanding, they have found inconsistent with their expectations, and the meaning of which they have failed to grasp. They have thus shattered every hope, and deprived themselves of the pure wine of the All-Glorious, and the clear and incorruptible waters of the immortal Beauty.

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 Ṣádiq 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.”

How strange! Notwithstanding these explicit and manifest references these people have shunned the Truth. For instance, mention of the sorrows, the imprisonment and afflictions inflicted upon that Essence of divine virtue hath been made in the former traditions. In the “Bihár” it is recorded: “In our Qá’im there shall be four signs from four Prophets, Moses, Jesus, Joseph, and Muḥammad. The sign from Moses, is fear and expectation; from Jesus, that which was spoken of Him; from Joseph, imprisonment and dissimulation; from Muḥammad, the revelation of a Book similar to the Qur’án.” Notwithstanding such a conclusive tradition, which in such unmistakable language hath foreshadowed the happenings of the present day, none hath been found to heed its prophecy, and methinks none will do so in the future, except him whom thy Lord willeth. “God indeed shall make whom He will to hearken, but We shall not make those who are in their graves to hearken.”
