"THIS Book which We have sent down is indeed abounding in blessings 1 and beareth witness to the Truth, so that the people may realize that the conclusive Proof of God in favour of His Remembrance is similar to the one wherewith Muḥammad, the Seal of the Prophets, was invested, and verily great is the Cause as ordained in the Mother Book. Chapter LXVI."
