Syedi Hasanji Badshah (Q.S.), the Author of ‘Kitaab-Ut-Tazkerat’ wrote that Shaikh Mohammed and Syedi Najam Khan were in prison with Syedna Qutbuddin (R.A). They were witness to the declaration of Nass by Syedna Qutbuddin (R.A) in favour of Syedna Shujauddin (R.A). Syedna Feerkhan (R.A) was detained in the prison after the demise of Syedna Qutbuddin(RA). King Shahjahan dismissed his son Laeen Aurangzeb and recalled Him to Jahanabad. Laeen Aurangzeb decided to take a chained and imprisoned Syedna Feerkhan (R.A) with him. Syedna(RA) told the Mumineen to perform Dua and Tadarro. Syedna FeerKhan (R.A) declared that Syedna Ismail Badruddin (R.A) who stayed in Jamnagar, would be the succeeding Dai-Al-Mutlaq. Laeen Aurangzeb reached Jahanabad along with Syedna Feerkhan Shujauddin (R.A). There He came to know that his father Sultan Shahjahan was in Lahore, so he went to Lahore and took Syedna Feerkhan (R.A) with Him. 
Syedna Feerkhan Shujauddin (R.A) who was imprisoned, was forced to wander from one place to another. Then one day a miracle occurred. Syedna(RA) was detained in a Raaoti (tent). Suddenly fire broke-out consuming every thing including the horses. But the 'Raaoti' (tent) did not catch fire in the midst of flames in which Syedna Feerkhan (R.A) was present. The Sultan came and inquired, “ Whose Raaoti (tent) is this? And why did it not catch fire “ Every one said, “We saw the flames getting extinguished on reaching this Raoti (tent)”. The Sultan came and asked Syedna FeerKhan (R.A), “Who are you”.and “What do you want?” He said “ I want nothing, what I want is to go back to my native place Ahmedabad.” Sultan ordered a gift and a horse to be given to Syedna Feerkhan (R.A) . Syedna Feerkhan (R.A) mounted the horse and Shaikh Mohammed and Syedi Najam Khan (Q.S.) got into the cart. 

Syedi Najam Khan (Q.S.) who was seriously ill, passed away on the way back, near Lahore. Then they reached Sironj, where Syedna was warmly received by mumineen . Then Syedna proceeded to Rampura where he stayed in a Masjid situated in the Mumineen locality. 

Syedna Shujauddin (R.A) visited villages inhabited by the Mumineen on the return journey till he reached Ahmedabad in the month of Ramazan in 1058 AH. In Ahmedabad he strived hard to bring Dawat to greater heights. The Munafeqin group did not like this development. All of them complained to Gairat Khan that,the followers of Syedna Qutbuddin (R.A) had collected rupees three lacs to ensure Syedna Qutbuddin's (R.A) release. The amount was still with their leader Syedna Feerkhan (R.A). GairatKhan dispatched fifty soldiers to arrest Syedna FeerKhan. Laeen Gairat Khan ordered Syedna to be imprisoned and enchained, and forwarded this case onward to the Sultan for decision. Six month passed but Syedna remained imprisoned. There was no communication from the royal Darbar. Then Syedna called one Ahmed bin Fateh Mohammed and asked him to go to the Sultan and get the release order signed. He specifically asked him to stay there and not to return unless he wasgiven razaa by Syedna . He went to Jahanabad but when considerable time passed with no result, he returned without waiting for Syedna's permission. Syedna was angry at his irresponsibility , disobedience and asked him to go away. That man went back to his home, and passed the night restlessly. The next day he went to the door of the prison but Syedna refused to see him. Ultimately he stopped coming.

There was another man who had embezzled the wealth of Dawat. He contacted Ahmed, and won him over to his side. Now both of them started instigating the nobles of the court. Inspite of their efforts to the contrary, after imprisonment of 18 months, Syedna was released from prison and went to the house of Syedi Shams Khan (Q.S.).  Yusufji and ChandMiya joined Laeen Ahmed. Syedna had entrusted the books to a man called Nooh. He too surrendered all those books at the instigation of Ahmed. All of them wrote a letter to Syedna Ismail Baddruddin (R.A) inviting them to be their accomplice. 

Syedna Ismail Badruddin (R.A) wrote from Jamnagar "You are foolish people, who would dare to disobey Dai-Al-Mutlaq's Farman. Allah will hang all ye who disobey Farman of Dai-Al-Mutlaq, upside down in Hell through the nostrils". 

The Munafeqin were bewildered to receive this answer, and Syedna(RA) was proud of Syedna Ismail Badruddin(RA) when He heard this news. 

It was Friday, people had gathered in the Masjid including Syedi Hasanji (Q.S.)(who rendered 'khidmat' (service), especially the procurement of water at night for 'Vazu'(ablution) for Syedna in prison). Syedna(RA) declared 'nass' - that the successor as Dai-Al-Mutlaq 'my ‘Qaim Maqam’' is Syedna Ismailji bin Raj (R.A).  Laeen Yusuf now started torturing Mumineen. He fell down on His face in the toilet. On the third day he died.  Laeen Chand Miyan too followed Laeen Yusuf’s footsteps, and started Fitnat. But within no time, insects filled his mouth, his tongue was swollen till he too perished. 

Laeen Ahmed surpassed these two in committing atrocities on the Mumineen. Syedna was performing Namaz in Rasulpura Masjid built by Syedna Qutbuddin (R.A). There Laeen Ahmed had started Namaz to be prayed parallel on the right side of Syedna at the same time, lead by him. Heavy debt had to be incurred during the period of Syedna Feerkhan (R.A), which was repaid by Syedna Ismail Badruddin (R.A). 

Syedna decided to travel to Hasanfeer Saheb. Syedna fell ill there and passed away on the 9th of Zilqaad 1065 AH.Syedna was laid to rest in the Qubbah Mubaraka of Syedna Qutbuddin (R.A).  After Wafat of Syedna Feerkhan Shujauddin (R.A), Syedna Ismail Badruddin (R.A) succeeded as Dai-Al-Multaq. The centre of the dawat shifted from Ahmedabad to Jamnagar after the Wafat of Syedna Shujauddin (R.A), initiating the chain of Duat-Badriyan.
