Say: This is that hidden knowledge which shall never change, since its beginning is with nine, the symbol that betokeneth the concealed and manifest, the inviolable and unapproachably exalted Name. As for what We have appropriated to the children, this is a bounty conferred on them by God, that they may render thanks unto their Lord, the Compassionate, the Merciful. These, verily, are the Laws of God; transgress them not at the prompting of your base and selfish desires. Observe ye the injunctions laid upon you by Him Who is the Dawning-place of Utterance. The sincere among His servants will regard the precepts set forth by God as the Water of Life to the followers of every faith, and the Lamp of wisdom and loving providence to all the denizens of earth and heaven.

God hath, likewise, as a bounty from His presence, abolished the concept of "uncleanness", whereby divers things and peoples have been held to be impure. He, of a certainty, is the Ever-Forgiving, the Most Generous. Verily, all created things were immersed in the sea of purification when, on that first day of Ridván, We shed upon the whole of creation the splendours of Our most excellent Names and Our most exalted Attributes. This, verily, is a token of My loving providence, which hath encompassed all the worlds. Consort ye then with the followers of all religions, and proclaim ye the Cause of your Lord, the Most Compassionate; this is the very crown of deeds, if ye be of them who understand.

Consort with all religions with amity and concord, that they may inhale from you the sweet fragrance of God. Beware lest amidst men the flame of foolish ignorance overpower you. All things proceed from God and unto Him they return. He is the source of all things and in Him all things are ended.

We, verily, see amongst you him who taketh hold of the Book of God and citeth from it proofs and arguments wherewith to repudiate his Lord, even as the followers of every other Faith sought reasons in their Holy Books for refuting Him Who is the Help in Peril, the Self-Subsisting. Say: God, the True One, is My witness that neither the Scriptures of the world, nor all the books and writings in existence, shall, in this Day, avail you aught without this, the Living Book, Who proclaimeth in the midmost heart of creation: "Verily, there is none other God but Me, the All-Knowing, the All-Wise."

It hath been forbidden you to carry arms unless essential
Bahá’u’lláh confirms an injunction contained in the Bayán which makes it unlawful to carry arms, unless it is necessary to do so. With regard to circumstances under which the bearing of arms might be “essential” for an individual, ‘Abdu’l-Bahá gives permission to a believer for self-protection in a dangerous environment. Shoghi Effendi in a letter written on his behalf has also indicated that, in an emergency, when there is no legal force at hand to appeal to, a Bahá’í­ is justified in defending his life. There are a number of other situations in which weapons are needed and can be legitimately used; for instance, in countries where people hunt for their food and clothing, and in such sports as archery, marksmanship, and fencing.
On the societal level, the principle of collective security enunciated by Bahá’u’lláh (see Gleanings from the Writings of Bahá’u’lláh, CXVII) and elaborated by Shoghi Effendi (see the Guardian’s letters in The World Order of Bahá’u’lláh) does not presuppose the abolition of the use of force, but prescribes "a system in which Force is made the servant of Justice", and which provides for the existence of an international peace-keeping force that "will safeguard the organic unity of the whole commonwealth". In the Tablet of Bishárát, Bahá’u’lláh expresses the hope that “weapons of war throughout the world may be converted into instruments of reconstruction and that strife and conflict may be removed from the midst of men”.
In another Tablet Bahá’u’lláh stresses the importance of fellowship with the followers of all religions; He also states that “the law of holy war hath been blotted out from the Book”.
