"Be fair to yourselves and to others, that the evidences of justice may be revealed, through your deeds, among Our faithful servants."

"Should such a man ever succeed in influencing anyone, this success should be attributed not to him, but rather to the influence of the words of God, as decreed by Him Who is the Almighty, the All-Wise. In the sight of God he is regarded as a lamp that imparteth its light, and yet is all the while being consumed within itself.
Say: Commit not, O people, that which will bring shame upon you or dishonor the Cause of God in the eyes of men, and be not of the mischief-makers. Approach not the things which your minds condemn. Eschew all manner of wickedness, for such things are forbidden unto you in the Book which none touch except such as God hath cleansed from every taint of guilt, and numbered among the purified.

Be fair to yourselves and to others, that the evidences of justice may be revealed, through your deeds, among Our faithful servants. Beware lest ye encroach upon the substance of your neighbor. Prove yourselves worthy of his trust and confidence in you, and withhold not from the poor the gifts which the grace of God hath bestowed upon you. He, verily, shall recompense the charitable, and doubly repay them for what they have bestowed. No God is there but Him. All creation and its empire are His. He bestoweth His gifts on whom He will, and from whom He will He withholdeth them. He is the Great Giver, the Most Generous, the Benevolent."
