Take ye good heed in your night (1) lest ye be a cause of sadness to any soul, whether ye be able to discover proofs in him or not, that haply on the Day of Resurrection ye may not grieve Him within Whose grasp lieth every proof. And when ye do not discern God’s testimony in a person, he will verily fail in manifesting the power of Truth; and God is sufficient to deal with him. Indeed on no account should ye sadden any person; surely God will put him to the proof and bring him to account. It behooveth you to cling to the testimony of your own Faith and to observe the ordinances laid down in the Bayán. (1) By ‘night’ is meant the period between two divine Revelations when the Sun of Truth is not manifest among men. In the Persian Bayán, II, 7, the Báb says, ‘O people of the Bayán! Act not as the people of the Qur’án have acted, for if you do so the fruits of your night will come to naught’. The Báb, Selections from the Writings of the Báb.
