We have been informed that thou hast forbidden the trading in slaves, both men and women. This, verily, is what God hath enjoined in this wondrous Revelation. God hath, truly, destined a reward for thee, because of this. He, verily, will pay the doer of good his due recompense, wert thou to follow what hath been sent unto thee by Him Who is the All-Knowing, the All-Informed.
- Bahá’u’lláh (Quoted by Shoghi Effendi, ‘The Promised Day Is Come’)
