Say: Should your conduct, O people, contradict your professions, how think ye, then, to be able to distinguish yourselves from them who, though professing their faith in the Lord their God, have, as soon as He came unto them in the cloud of holiness, refused to acknowledge Him, and repudiated His truth? Disencumber yourselves of all attachment to this world and the vanities thereof. Beware that ye approach them not, inasmuch as they prompt you to walk after your own lusts and covetous desires, and hinder you from entering the straight and glorious Path.
