It was on 22 January 1844, twenty-two days after the death of Siyyid Káẓim, that Mullá Ḥusayn returned to Karbilá. For three days he received visitors at his home, all of whom expressed their sorrow because of the passing of Siyyid Káẓim. After listening to their cries he invited the most trusted and outstanding ones to tell him what Siyyid Káẓim had told them to do before he died. They told him that Siyyid Káẓim had said over and over, ‘You must leave your homes, travel far and wide, purify your hearts, and search for the Promised One. The only way you can find Him is to search. You must pray to make your hearts pure - and search.’
When Mullá Ḥusayn heard these words he said, ‘Then why are you still here in Karbilá? Why have you not scattered all over the land? Why have you not followed Siyyid Káẓim’s wish?’
They answered: ‘It is true we have failed. But, we look to your greatness. We have such confidence in you that if you were to tell us that you are the Promised One yourself, we would believe it and obey you in anything you told us to do.’
‘God forbid!’ said Mullá Ḥusayn. ‘I am just dust compared to the Promised One, the Lord of Lords. If you had really understood the message of Siyyid Káẓim, you would never have spoken such words! No! What you must do - and what I must do - is to arise immediately to carry out Siyyid Káẓim’s message.’
Suiting his action to his words, Mullá Ḥusayn immediately stood up and went to deliver this message to other well-known followers of Siyyid Káẓim. Some of them made excuses that they could not leave Karbilá at this time, and a few accepted Mullá Ḥusayn’s words as the truth.
Mullá Ḥusayn, himself, wasted no time. Together with his brother, Muḥammad-Ḥasan, and his brother’s son, Muḥammad-Báqir, he set out for Najaf. On the way to Najaf they stopped at a place for forty days to fast and pray and purify themselves for their search for the Báb. Then they went on to Búshihr, on the Persian Gulf.
