“Say: it is a weighty Message, from which ye turn aside!” Qur’án 38:67

"Although the outward meaning of “Whom God causeth to err through a knowledge” is what hath been revealed, yet to Us it signifieth those divines of the age who have turned away from the Beauty of God, and who, clinging unto their own learning, as fashioned by their own fancies and desires, have denounced God’s divine Message and Revelation. “Say: it is a weighty Message, from which ye turn aside!” 15 Likewise, He saith: “And when Our clear verses are recited to them, they say, ‘This is merely a man who would fain pervert you from your father’s worship.’ And they say, ‘This is none other than a forged falsehood.’” 16


Give ear unto God’s holy Voice, and heed thou His sweet and immortal melody. Behold how He hath solemnly warned them that have repudiated the verses of God, and hath disowned them that have denied His holy words. Consider how far the people have strayed from the Kawthar of the divine Presence, and how grievous hath been the faithlessness and arrogance of the spiritually destitute in the face of that sanctified Beauty. Although that Essence of lovingkindness and bounty caused those evanescent beings to step into the realm of immortality, and guided those destitute souls to the sacred river of wealth, yet some denounced Him as “a calumniator of God, the Lord of all creatures,” others accused Him of being “the one that withholdeth the people from the path of faith and true belief,” and still others declared Him to be “a lunatic” and the like."
