During this time He revealed the following:

Also during this period the decline and breakdown of the Ottoman Empire continued. It was often referred to as the "Sick Man of Europe." This decline was characterized by administrative inefficiency, territorial losses, and the rise of nationalist movements in many of its provinces.

Bahá'u'lláh and His companions arrived in Adrianople (the "remote prison") ("The Land of Mystery") (GPB174). It would be here where the sun of His revelation would ascend to its zenith, where He proclaimed the Message of His revelation to the whole world. [BKG206; GPB161; RB2:62]

Upon arrival He and His family were driven to the residence of Shamsi Big near the Sharif Mosque. They stayed here about one month. His companions were given accommodation elsewhere in the city. [BKG197, 204; GPB157–61, HDBFXXVIII]

1. He forbade the use of the sword.
2. He stated that no other Manifestations will appear before one thousand years. This was later reiterated in the Kitáb-i-Badí' and in The Kitáb-i-Aqdas.
3. He stated that, as from that moment, all the names and attributes of God were manifested within all created things, implying the advent of a new Day. [RB1:278–80]

During the 12 days in the Ridván Garden Bahá'u'lláh confided to 'Abdu'l-Bahá that He was 'Him Whom God shall make manifest'. [CH82]

The garden was located in a large agricultural area immediately north of the walls of the city of Baghdad, about 450 metres (1,480 ft) from the city's northern Mu'azzam gate. Located on the eastern bank of the Tigris River in what is now the Bab al-Mu'azzam neighbourhood of Baghdad's Rusafa District, it was directly opposite the district in which Bahá'u'lláh lived during his stay in the city, on the river's western bank.

Extract from a Tablet of Baha'u'llah-Khadimu'llah. (Edited provisional translation below)

"On the first day that the Ancient Beauty occupied the Most Great Throne in a Garden which hath been designated Ridván, the Tongue of Grandeur uttered three blessed verses.
[1] The first of them was that in this Manifestation the use of the sword in holy war is put aside.
[2] Secondly, prior to the completion of a millennium any theophanological claim put forward by any person must be considered baseless. In this respect the year should be considered a complete year.
[3] Thirdly, the True One, exalted be His Glory, at that time manifested all the Divine Names upon all things.
"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". [Kitab-i-Aqdas para75 p47]

And the following choice verse was subsequently revealed but has been ordained to be of the same rank as the preceding three; namely, whatever personal designations are mentioned before the Face, whether living or dead, such have thereby attained the Presence of God by virtue of being mentioned by the King of Pre-Existence. [UCMERCED site]

• There is a tradition in Islam quoted by Shoghi Effendi in his Persian writings which sets forth the difficulties and perils encountered by man on his journey to God. It describes how all men will perish and die except the believers; all the believers will perish and die except those who are tested, all who are tested will perish and die except those who are sincere, and those who are sincere will be in great danger.
