"Syed Imam Shah was a famous Ismaili da'i in India. His name was Imamuddin, surnamed Abdur Rahim. He was born in Uchh Sharif in 834/1430, and was the younger son of Pir Hasan Kabiruddin. The tradition has it that when Pir Hasan Kabiruddin died, his all sons were present at Uchh Sharif with exception of Syed Imam Shah. The tradition attests that he reached late during the interment of his father's body. Many traditions are recounted for his dissatisfaction, but all are legendary in character.

Syed Imam Shah resided at Uchh Sharif with his sister called Bai Budhai, where he received a letter of Imam Muhammad bin Islam Shah through a certain Khoja Devasi Chandan. Hence, he started his journey for Kahek in 854/1450. Imam Muhammad bin Islam Shah is said to have commissioned him the mission for Gujrat. He returned and converted a bulk of Hindus in Gujrat. He got married to the daughter of Shah Muhammad Bakhri, who gave birth of Syed Nur Muhammad Shah (d. 940/1534). Syed Imam Shah died in 926/1520 and was buried in Pirana, situated ten miles south-east of Ahmadabad. It is said that he abjured Ismailism because of being failed to succeed his father, but it is not in conformity with the genuine traditions. Weighing up the extant evidences, it appears that he was ingrained in Ismailism and demonstrated unswerving loyalty to the Imams till his death, and never took any other route to perpetuate his so called ambition. According to The Shorter Encyclopaedia of Islam (Leiden, 1961, p. 167), "As far as it is possible to ascertain, he cannot be regarded as the founder of a new sect, as he remained loyal to the Imam of his time." He wrote many ginans which are recited by the Ismailis. He had four sons, viz. Syed Alam Shah, Syed Ali Shah, Syed Bakir Shah and Syed Nur Muhammad Shah, and a daughter called Shams Khatoon.
