In the Book of Utterance these exalted words have been written down and recorded: “Say, O friends! Strive that haply the tribulations suffered by this Wronged One and by you, in the path of God, may not prove to have been in vain. Cling ye to the hem of virtue, and hold fast to the cord of trustworthiness and piety. Concern yourselves with the things that benefit mankind, and not with your corrupt and selfish desires...”
—Bahá’u’lláh, Epistle to the Son of the Wolf
