... speech and utterance ...

Blessed is the spot wherein the anthem of His praise is raised, and blessed the ear that hearkeneth unto that which hath been sent down from the heaven of the loving-kindness of thy Lord, the All-Merciful.
Exhort thou the servants of God unto that whereunto We have exhorted thee that they may abstain from whatsoever is forbidden them in the Mother Book. Those who perpetrate deeds that would create turmoil among the people have indeed strayed far from helping God and His Cause and are numbered with the mischief-makers in the Tablet which God hath designated to be the dawning-place of all Tablets.
Say: If it be Our pleasure We shall render the Cause victorious through the power of a single word from Our presence. He is in truth the Omnipotent, the All-Compelling. Should it be God’s intention, there would appear out of the forests of celestial might the lion of indomitable strength whose roaring is like unto the peals of thunder reverberating in the mountains. However, since Our loving providence surpasseth all things, We have ordained that complete victory should be achieved through speech and utterance, that Our servants throughout the earth may thereby become the recipients of divine good. This is but a token of God’s bounty vouchsafed unto them. Verily thy Lord is the All-Sufficing, the Most Exalted.
