"It is indeed the sign of God that hath been sent down through the power of truth, through which the validity of His Cause hath been demonstrated unto His creatures, and the ensigns of purity lifted up betwixt earth and heaven."

"Go forth with the Tablet of God and His signs, and rejoin them that have believed in Me, and announce unto them tidings of Our most holy Paradise. Warn, then, those that have joined partners with Him. Say: I am come to you, O people, from the Throne of glory, and bear you an announcement from God, the Most Powerful, the Most Exalted, the Most Great. In mine hand I carry the testimony of God, your Lord and the Lord of your sires of old. Weigh it with the just Balance that ye possess, the Balance of the testimony of the Prophets and Messengers of God. If ye find it to be established in truth, if ye believe it to be of God, beware, then, lest ye cavil at it, and render your works vain, and be numbered with the infidels. It is indeed the sign of God that hath been sent down through the power of truth, through which the validity of His Cause hath been demonstrated unto His creatures, and the ensigns of purity lifted up betwixt earth and heaven."
