He [the Báb] then proceeded to say:“Now is the time to reveal the commentary on the Súrih of
Joseph.[of Qur’an]” He took up His pen and with incredible rapidity
revealed the entire Súrih of Mulk, the first chapter of His commentary on the
Súrih of Joseph. The overpowering effect of the manner in which He wrote was
heightened by the gentle intonation of His voice which accompanied His writing.
Not for one moment did He interrupt the flow of the verses which streamed from
His pen. Not once did He pause till the Súrih of Mulk was finished. I sat
enraptured by the magic of His voice and the sweeping force of His revelation.”
- Mulla Husayn (Quoted by Nabil in chapter 3 of ‘The Dawn-Breakers’)
