Mulla Muhammad, the chief divine of the district of Nur asked his two trusted sons-in-law, Mulla 'Abbas and Mirza Abu'l-Qasim to meet Baha’u’llah and determine the true character of the Message that He had brought. He pledged his unreserved endorsement of whatever conclusions they might reach.
On being informed, upon their arrival in Tákúr, that Bahá’u’lláh had departed for His winter resort in Darkala, the representatives of Mullá Muhammad decided to leave for that place. Darkala is located north of Takur, closer to the Caspian Sea. It has a milder, rainy weather. Baha’u’llah’s father had a winter house in Darkala for the use of his extended family who didn’t live in Tehran. The two envoys had to travel over the mountains to get to their destination.
