Kitáb-i-Aqdas

The Lord hath prohibited ... the practice to which ye formerly had recourse when thrice ye had divorced a woman.   ¶68

This relates to a law of Islám set out in the Qur'án which decreed that under certain conditions a man could not remarry his divorced wife unless she had married and been divorced by another man. Bahá'u'lláh affirms that this is the practice which has been prohibited in the Kitáb-i-Aqdas (Q and A 31).
