It was during Syedna Abdultayeb Zakiuddin's (R.A) era when Syedna Ismail Badruddin (R.A) was born in Udaipur on the twenty-seventh of Zilhajjatil Haram, 1097H. His early childhood was passed in Udaipur with his parents Syedi Shaikh Adam (Q.R) and mother Fatema Aaisaheba. After the sad demise of his mother in Mandvi and his father Syedi Shaikh Adam (Q.R) soon after, Syedna Ismail's (R.A) upbringing was undertaken by his grandfather Syedna Abdultayeb (R.A). At the age of fifteen Syedna Abdultayeb (R.A) took Misaq of Syedna Ismail (R.A) and sent him for Dawat to Mandvi. Syedna Ismail (R.A) later married Jeevna Baisaheba daughter of Syedna Noor Mohammed Nooruddin Saheb (R.A). He was granted the honored Rutba of Mukasir by Syedna Nooruddin (R.A) and was shortly elevated to the eminent position of Mazoon. Syedna Nooruddin (R.A) than performed Nass upon him.

Subsequent to the sad demise of Syedna Nooruddin (R.A), Syedna Ismail (R.A) ascended the high seat of Dai and appointed Syedi Abdul Qader Hakimuddin (Q.R) as Mazoon and also performed Nass upon him. On the event of the death of Syedi Abdul Qader Hakimuddin (Q.R), Syedna Ismail (R.A) appointed Syedi Qazi Khan Saheb (Q.R) as Mazoon who too soon passed away. Syedna Ismail's (R.A) affection upon students was evident. Under his beneficial guidance, a Masjid and Madrasa were constructed in Mundra.
