Source (Persian)
نزاع و جدال را نهی فرمود نهيا عظيما فی الکتاب * هذا أمر اللّه فی هذا الظّهور الأعظم و عصمه من حکم المحو و زيّنه بطراز الإثبات إنّه هو العليم الحکيم *
Translation
Conflict and contention are categorically forbidden in His Book. This is a decree of God in this Most Great Revelation. It is divinely preserved from annulment and is invested by Him with the splendour of His confirmation. Verily He is the All-Knowing, the All-Wise.
