Bahá’u’lláh had no intension to go back to Baghdád

…in Our solitude We were unaware of the harm or benefit, the health or ailment, of any soul. Alone, We communed with Our spirit, oblivious of the world and all that is therein… Our withdrawal contemplated no return, and Our separation hoped for no reunion. The one object of Our retirement was to avoid becoming a subject of discord among the faithful, a source of disturbance unto Our companions, the means of injury to any soul, or the cause of sorrow to any heart. Beyond these. We cherished no other intention, and apart from them. We had no end in view. 

- Bahá’u’lláh (‘The Kitab-i-Iqan)

 

Bahá’u’lláh’s family didn’t know where He went

One morning, the household of Bahá’u’lláh awoke to find Him gone. And no one knew where to seek Him. That day was 10 April 1854. It was to Sulaymáníyyih, in the heart and uplands of Kurdish ‘Iráq, that Bahá’u’lláh had turned for seclusion.

10 April 1854: Bahá’u’lláh left Baghdád

Seeing that his presence in Baghdád was in danger of splitting the community, Bahá’u’lláh decided to leave the scene of the conflict for the mountains 300 kilometers to the north of Baghdád which are the domains of the Kurdish people. He took with him one attendant, Aqá ‘Abu’l-Qásim Hamadáni, who was not well- known among the Bábís, and left suddenly, informing no-one of where He was going.
