He was the son of Syedna AbdulHusain Husamuddin, whose family lineage can be traced back to Syedi Fakhruddin Shaheed.

[1] He was educated by his father in all fields of knowledge and he always remained at the service of his uncle, for the active part of his childhood and youth until age 39, helping him and also learning from him.

Later he also served the 49th Da'i al-Mutlaq Syedna Mohammed Burhanuddin for fifteen years with great dedication and responsibility.

His childhood was greatly influenced by the Dawoodi Bohra culture, traditions and principles being brought up in a family of Da'i al-Mutlaq.

[3] Thus the knowledge imparted by the 43rd Da'i al-Mutlaq Syedna Abde'Ali Saifuddin traveled a time gap of a hundred years and reached its rightful person, without being disrupted by the learned enemies of the Dawoodi Bohra sect.

During the era of Syedna AbdulQadir Najmuddin, a 'Hadd-e-Fadil' (a high ranking learned person) of the Dawoodi Bohra sect had predicted the glorious future of Abdullah Badruddin.

[1] Abdul Qadir Najmuddin paid special attention towards all aspects of his upbringing and education along with his brother Syedi Abdeali Moyyuddin.

A time when the enemies of the Dawoodi Bohra community hatched a conspiracy stating that nas has not been conferred over Abdul Qadir Najmuddin by the 46th Da'i al-Mutlaq Mohammed Badruddin.

His cousin brother charted out a plan[6] to get the debt ridden Dawoodi Bohra sect out of its dues and free from the shackles of the lenders.

So much so that he would leave early in the morning, hire a carriage and visit shops to collect funds, even at the time of lunch he would continue the work at hand and after coming home he would eat alone.

Seeing his dedication one of his uncles commented saying that, 'the one whom he is serving day and night doesn't even wait for him (to have food together)', referring to his cousin brother.

Due to all the efforts of three Da'i al-Mutlaq Abdul Qadir Najmuddin, Abdul Husain Husamuddin and especially due to the planned efforts of 49th Da'i al-Mutlaq Mohammed Burhanuddin, when the helm of Dawoodi Bohra sect came into his hands there was prosperity and development all around in the Dawoodi Bohra community.

Seeing him perform the waaz the belief of the learned members of the community was reaffirmed, that the grace and blessings of the Imam in seclusion is with him.

Abdullah Badruddin with his knowledge and persuasive tact brought back many members of the Dawoodi Bohra sect who had been deceived by the enemies claims.

When his father Abdul Husain Husamuddin became the 48th Da'i al-Mutlaq there were huge debts over Dawoodi Bohra sect.

[6] He also helped his cousin brother in setting up an efficient and effective organisational structure[6] to ensure the smooth functioning of the various offices of the community.

And within a period of five years all the departments were functioning like a single unit allowing the Dawoodi Bohra sect to take off on its developmental flight.
