Shun

Shun them whose hearts are turned away from thee, and place not thy confidence in them, and entrust them not with thine affairs and the affairs of such as profess thy faith. Beware that thou allow not the wolf to become the shepherd of God's flock, and surrender not the fate of His loved ones to the mercy of the malicious. Expect not that they who violate the ordinances of God will be trustworthy or sincere in the faith they profess. Avoid them, and preserve strict guard over thyself, lest their devices and mischief hurt thee. Turn away from them, and fix thy gaze upon God, thy Lord, the All-Glorious, the Most Bountiful.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 233

And now, one of the greatest and most fundamental principles of the Cause of God is to shun and avoid entirely the Covenant-breakers, for they will utterly destroy the Cause of God, exterminate His Law and render of no account all efforts exerted in the past.

‘Abdu’l-Bahá, The Will and Testament, p. 20

But the more the tormenting friends shun thee, go thou nearer to them. The more they deride and blame thee, show thou forth the greater love and affection. Do not look upon their shortcomings. Look thou upon all of them as the people of God and endeavour thou in right-doing and well-meaning. Ignorant are they; understand they do not. Therefore they are avoiding, criticizing and scorning thee.

‘Abdu’l-Bahá, Lights of Guidance, p. 162

He said, "Verily, shun those who are shaken in the Covenant.

‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 382

He said, "Whosoever believes in Him is acceptable in the estimation of God, and whosoever shuns Him or any of the prophets is rejected of God.

‘Abdu’l-Bahá, The Promulgation of Universal Peace, p. 409

Many utterances are directed against the violators of the Covenant, the purpose being that no dissension should arise in the blessed Cause; that no one should say, "My opinion is this"; and that all may know Who is the authoritative expounder and whatsoever He says is correct. Bahá’u’lláh has not left any possible room for dissension.
