Backbiting, slander and dwelling on the faults of others have been repeatedly condemned by Bahá'u'lláh. In the Hidden Words, He clearly states: "O Son of Being! How couldst thou forget thine own faults and busy thyself with the faults of others? Whoso doeth this is accursed of Me." And again: "O Son of Man! Breathe not the sins of others so long as thou art thyself a sinner. Shouldst thou transgress this command, accursed wouldst thou be, and to this I bear witness." This strong admonition is further reiterated in His last work, "the Book of My Covenant": "Verily I say, the tongue is for mentioning what is good, defile it not with unseemly talk. God hath forgiven what is past. Henceforward everyone should utter that which is meet and seemly, and should refrain from slander, abuse and whatever causeth sadness in men."
